Top 4 Free Meeting Software Online.

Online meetings have become very popular in the world. However, in some countries, many businesses have not yet implemented. Partly because of the high cost of investment, but more important is the traditional meeting habits that are embedded in corporate culture. So, today I would like to introduce you to 4 online meeting software completely free. Businesses can try out their small team meetings to see how well they are doing before deciding to invest in larger systems.

1. Skype

Skype is a very popular software in the world. Skype allows texting, making free audio calls or video calls. In recent times, Skype has added features that allow group video calls to be made available in small online meetings.

a. How to use:

Because it’s so popular, Skype supports most platforms from Computer to Mobile, Tablet or even TVs, Xbox consoles. With a free account, you can use up to 100 hours per month, 10 hours per day and 4 hours per meeting. When exceeded by the time limit, your meeting will automatically switch to normal voice call mode.

Skype does not mention the maximum number of people that can participate in the meeting, but recommends users not to be meeting more than 5 people. In fact, this issue is very much dependent on the amount of people using Skype and international Internet access (due to Skype’s overseas server).

b. Performance:

On the quality of voice, I probably do not need to talk much, Skype uses the SILK codec developed by Skype itself for very good quality. In terms of image, Skype uses the open source codec VP8 developed by Google and H.264. These two standards are quite popular so it is no different from other software. Therefore, stability will be ensured.

2. Google Hangout

The second software I would like to introduce to you in today’s article is Google Hangout. This is a gadget that comes with Google plus. Users can immediately use their Gmail account to use. Extremely convenient and friendly.

a. How to use:

Google Hangouts can run live on the Chrome browser so you can use it with any type of computer. On mobile, Google Hangout supports two popular platforms, iOS and Android. Of course, since it’s a Google product, Google Hangouts runs best on Android devices.

Like most other Google services, Hangouts is free. With up to 10 people in Group Video Call calls, Hangouts can support most small online meetings. (The fact that free services rarely guarantee quality when meeting more than 5 people).

b. Performance:

Google has its own open source video encoder VP8. However, Google uses Vidyo’s proprietary codec. This is the new H.264-SVC standard technology for better “fixing bugs” and is able to adapt to low-quality lines such as 3G.

Image quality of Google Hangout is relatively good, especially in countries with poor Internet quality like some Asian countries. However, the software running as an add-in of Browser also has many limitations on features, as well as not fully exploit the performance of high-configuration computer.

3. TrueConf Online

TrueConf is a leading videoconferencing software provider in Russia. In line with the world’s cloud trend, TrueConf also offers its TrueConf Online service based on its TrueConf Server platform.

a. How to use:

TrueConf also supports most PC and mobile operating systems, and supports WebRTC on Chrome and Firefox browsers. TrueConf Online only allows up to 3 points free. You can extend up to 250 points, but of course you have to pay extra. TrueConf also allows users to download server software to manually install a dedicated video conferencing system.

TrueConf has 4 meeting modes for different purposes: picture call (resolution to fullHD), multi-point video conferencing, online class, virtual meeting room (4K resolution).

b. Performance:

TrueConf Online gives you very good picture quality. You may find it quite similar to Google Hangout. Because TrueConf also uses the H.264-SVC encoder on VP8. However, because of the service fee, the quality is guaranteed. If you are a business, need security and stability, you should install TrueConf on your own server and purchase one license.

4. VSEE

Unlike current online conferencing software, VSEE is quite special when using a peer-to-peer connection model instead of a central server. The software on the user’s computer sends and receives images directly to each other.

a. How to use:

Theoretically, by using the peer-to-peer connection model, VSEE can extend unlimited number of meeting points. However, this depends a lot on your computer’s configuration. The computer itself must handle all the connections that can lead to overload if there are too many points involved. Another downside is that you cannot control the meeting, so it is suitable for workshops, team work.

VSEE does not currently support Linux. And for iOS, it only runs on the iPad, not the Iphone.

b. Performance:

Depending on computer configuration and transmission quality, VSEE will give very different quality. But overall with small groups of 4-5 people, the image quality is relatively good. VSEE does not release information about audio encoders as well as images, but it seems they write their own encoders.

Link: http://pixelart.studio/

Whether you’re a game developer or just a fan of 8-bit classical art, you’ll probably love Pixel Art Studio. Along with common features like hand-drawing and fill-in, this software also lets you create animations.

At the very beginning, you choose the background size and hand draw or straight line tool. For geometric designs, you can mirror the image by the X or Y axis once you have finished painting one side. Once you’ve finished sketching, it’s time to color the composition. Like Photoshop, the custom palette lets you drag and drop colors from the color palette and save them. Meanwhile, you can track your finished work in the preview window.

Creating GIF images with Pixel Art Studio is also easy. Using the animation toolbar at the bottom of the window, you can create a frame sequence and specify the transition speed. Even, the tool has a “onion skin” mode to smooth the transition of the frame.

When you export to PNG or GIF, Pixel Art Studio has a slider for you to select the pixel spacing, as well as the ability to set the background and the pixels to be set. Then, you can insert your work in the indie game format, and share it with the Pixel Art Studio community.

6. Focus Writer

https://gottcode.org/

Have you ever had to write a long post, but sometimes glances at Facebook for new information or surfed through YouTube? The FocusWriter text editor will help you get rid of all your other annoying applications so you can focus on your work.

The FocusWriter automatically enters the full-screen mode when you open the “editor” environment, blocking all other windows and leaving you just facing a “blank sheet” of the screen. You can hover your mouse over the menu to show the application, with several format options. However, FocusWriter has some hidden hints.

First, there is a default add-on, consisting of traditional black-and-white, or wood-based themes with a variety of background images, such as forest photos or thunderstorms. If those photos do not appeal to you, let create your own theme by uploading a photo of yourself and choosing other fonts and colors to your liking.

First, there is a default add-on, consisting of traditional black-and-white, or wood-based themes with a variety of background images, such as forest photos or thunderstorms. If those photos do not appeal to you, create your own theme by uploading a photo of yourself and choosing other fonts and colors to your liking.

You can also set up Daily Goal goals, which can be calculated according to the writing time or number of words that one day needs to complete, for example an hour or 1,000 words, and the application has a bar at the bottom of the screen which will tell you the progress of completion. Your goals will be saved in a calendar, like a health monitoring application, and rewarded with “winning streaks” if you reach your goal for several days in a row.

Other useful tools of this utility include the ability to gray out every other text except for the single line or paragraph you are typing, an alarm clock and a spell checker. Even if you prefer, you can turn on sound typing on the typewriter keyboard, even if this feature is turned on, which may upset colleagues sitting next to them.

FocusWriter’s files can be saved in text format (TXT), rich text (RTF), Open Office XML (DOCX) and OpenDocument Text (ODT). This is supposed to be a good text-to-speech software that will keep you focused.

7. SketchUp

Link: https://www.sketchup.com/

After being sold by Google to Trimble Navigation in 2012, SketchUp Make is getting better and the 2017 version of the tool is no exception. This is a very powerful 3D rendering application, suitable for anyone working in the field, from professional architects to beginner to professional.

SketchUp’s interface at first can be confusing, but the more you use it, the more you can feel its simplicity in creating 3D cubes. For example, to create a 3D template from a 2D drawing, you simply sweep the mouse from the bottom with the Pull tool, as if you pulled the wall from the floor to the ceiling. The Instructor menu box in the default tray is also very handy, as it will guide you through familiar, easy-to-understand animations.

SketchUp has many features for you to create realistic looking 3D models, including shaders, surface coatings made of materials such as wood and brick, or tape measure lengths, animations … and even have the feature set 3D drawings into the real environment, based on imagery from Google Maps. In addition, you can explore and download a variety of designs from the “3D Warehouse” community, including famous buildings such as Westminster Castle.

8. Levelator

Link: http://conversationsnetwork.org/levelator

Perhaps the Levelator tool is less widely known, as it is only for those who do audio production, podcasting, or other audio programs. But with these objects, Levelator is the best free tool available today. It simply smooths out different volume levels in the audio file, to create a more consistent record.

At first glance, it looks like nothing magical, but the Levelator is smarter than other tuning tools. Not only does the simple task mentioned above, this tool also analyzes the entire spectrum to identify the average volume level, then compensates for too high and too low volume. So, if you record an interview, a conversation between two people, in which one voice is smaller than the other, Levelator will recognize this “gap” of sound and will correct themselves both The voice is more equal in volume. This feature saves a lot of time for you.

Unfortunately, Levelator is no longer focused on development, as Conversations Network, the organization dedicated to podcasting and sponsorship for the development of this tool, has shut down since 2012. Although the final version of Levelator is still online and works very well but it may still need some maintenance and development.

9. Wunderlist

Link: https://www.wunderlist.com/

Unlike other to-do list management applications, Wunderlist is simple. There are options for you to set deadlines, create sub-tasks and add notes and attachments to tasks, but the power of this tool is to be able to quickly note when you need to take notes something. Sharing the task list with others of the Wunderlist is also very easy.

Job lists can be broken down into a variety of topics, making it easy to divide tasks by company, individuality … although the default Inbox window displays all tasks in sequence Wunderlist is also compatible with many operating system platforms, but it is now owned by Microsoft.

10. Unleashed Evernote

Link: https://evernote.com/

While not having as many features as OneNote from Microsoft, Evernote Basic is a very powerful workflow tool.

Its look is more traditional than OneNote, which includes standard Office fonts, text color, tables, and highlighting tools. However, Evernote has some very unique tricks, including the ability to attach a Google Drive file, record it directly in the app, and embed it into a note, insert a source code and set up email reminders. Another great feature is the ability to set a secure password when opening this app on your phone.

Once you create a note, add it to your notebook and sync Evernote Basic on two devices, you can use a browser extension called Web Clipper to save an entire web page to the notebook for later reading. You can also add notes and tags to your notes, as well as share them with others via email or social networking.

The only problem with Evernote Basic is that it’s pretty basic: 60MB of uploads a month are pretty tight. If you want more space, you’ll need to pay a premium for upgrading to Evernote Plus or Premium. But this is a great tool for notes if you want to add notes and images.

11. Unleashed OneNote

Link: https://www.onenote.com/

I must say that OneNote is not the best free software, but the OneNote version of Microsoft’s Windows Store is an excellent tool for anyone, from students to senior entrepreneurs.

With a paper-like interface, OneNote has many useful features such as a multi-page handbook, highlight tool, various drawing tools (including color palettes for you to paint creatively). , insert images easily, add attachments, insert tables, insert items to-do list, and have a slider for you to see how you note over time.

In particular, OneNote has an impressive feature called Ink Match Assistant, converts handwriting into text and offers tips to make. This is a great learning aid for both teachers and students. In addition, you can use your device’s camera to quickly import paper documents into an OneNote file without wasting much time scanning documents.

OneNote also automatically syncs your notebook to the cloud, but you can also create a share link, meaning your friends and coworkers without OneNote installed will also be able to view your notes, and even you. The notebook can be downloaded directly to Twitter. You can also use OneNote without a network connection, so it’s a great fit for you on long trips.

12. Slack

Link: https://slack.com/

Maybe I can – not say all the great features of Slack, which is the best collaboration tool, even though other competitors such as Flock (flock.co) or Microsoft Teams have come up with potential. The highlight of Slack is that it’s free.

Another attractive element of Slack is its multi-platform support, including Windows, MacOS and Android, and it’s easy to share and view files. Tools like “remind me” help Slack better because it tells you what is the priority.

13. PhraseExpress

Link: http://www.phraseexpress.com/

Compatible with many programs, including Microsoft Office and most browsers, PhraseExpress can help you breathe easier by placing text, images, templates, web links, forms and documents when you type a certain phrase.

But the real attraction of PhraseExpress is its features and the ability for users to customize the macro command. For example, you can set a time delay before the word automatically appears (in milliseconds), insert images, and only run macros on specific programs, such as Google Chrome or Microsoft Word. For example, you might be interested in typing the word “rice”, a rice bowl image that appears in Word in 150 milliseconds.

And to avoid accidentally sending the rice bowl image to your boss, you can keep those shortcuts in the folder and set PhraseExpress’s password protection. This tool saves a lot of time and effort for you.

The best free software – 17 utilities needed for PC – Part 1

Sometimes, if you use software, you can solve problems easily, but you do not always realize that. So, in this article I will choose the best free software for Windows (also available on other platforms), focusing on three distinct categories.

1. 7-Zip

  • Link homepage: http://www.7-zip.org/
  • The first application I would like to introduce to you in this article is 7-Zip. This is a great compression and decompression tool on the internet today. Maybe you think that you do not need it because Windows also has the ability to create and extract ZIP files by default, but 7-Zip has many other benefits. It supports a lot of file formats: it opens most of the compressed files on the internet, which includes very popular RAR files. It also allows you to browse and extract files from ISO image files, VDI, VHD and WIM, installation files such as CAB and MSI, even giving you access to the macOS DMG file.
  • Another advantage of 7-Zip is its ease of use. After installation, the application adds a submenu to the right-click menu in Windows Explorer, meaning you can compress and decompress files and folders with a single click. For more professional users, this utility also has a command line interface.
  • The best feature of 7-Zip is better compression than Windows, especially when you use its default compression format of 7z. According to the developers, the efficiency of file compression is up to 70% better than the normal ZIP compression format. A self-extracting compression format means that your colleagues can open compressed files without installing 7-Zip. Another factor is the “AES-256 encryption tool” for the password, so if compared to the built-in compression / decompression tool of Windows, 7-Zip is a lot better.

2. 7+ Taskbar Tweaker

  • Link: http://rammichael.com/
  • You do not necessarily have to use the Windows taskbar, because 7+ Taskbar Tweaker gives you many more great options. Taskbar Tweaker has three main sections: “Taskbar Items”, “Grouping and Combining” and “Other Taskbar Options”. And this is the second application I would like to introduce to you in this article.
  • The first item includes the ability to change what happens if you right-click or hover a thumbnail icon. The second item determines how the application is grouped on the taskbar, with the option of disabling grouping or browsing through windows by clicking the left mouse button. The third item contains a shortcut option when you double-click an empty spot on the taskbar to pop up the Task Manager or Start menu, switch back and forth between auto-hide / hold the taskbar and open the Taskbar Inspector. The Inspector displays all information about what applications are running, plus you can hide the Start button and display “seconds” of the clock in the clock interface.

3. Everything

  • Link download: http://voidtools.com/
  • The third application I would like to introduce to you is Everything. This is one of the simplest software in this article. Everything is a fast way to find files and folders on your PC. According to this site, the software takes only a second to create an index for 70,000 files, so 1 million index files only take about 1 minute. And the preliminary test also says this. You can also narrow down your search by filters. As you can find just the document file, audio file, compressed file, executable file, image, video or just the directory. While the asterisk (*) will represent a group of characters. For example, if you search for “t * m” for a file, the result is a series of files with the first letter “t” and the last letter “m”. Or you can use the Boolean AND (space), OR (“|”) and NOT (“!”) to filter the search. Simple, fast, efficient is what Everything can search for instead of the integrated search engine of the operating system.

5. CCleaner

  • Link download: http://www.piriform.com/
  • The fourth application I would like to introduce in this article is Ccleaner. To speed up your Windows or Mac computer, CCleaner is a neat little tool that has a very powerful engine. The CCleaner tool is usually divided into two lists for you to choose from: Windows and Applications. Applications include standard features such as the Recycle Bin, deletion of temporary files created by the system, and deletion of cache data of the Microsoft Edge browser.
  • The good thing about the tickbox ticker system is that you can exclude individual files or programs that are not cleaned by CCleaner, and it also tracks how much space is left over the window. You can also run an analytics tool before the files are deleted, to make sure not to accidentally delete any unwanted files.
  • Registry cleanup is similar and very easy to use, allowing you to completely remove software, files, paths, fonts, ActiveX issues and redundant installers. Again, CCleaner is very useful to users thanks to the “Scan for Issues” button. This button will list the problems that the system encounters and has the option to restore the registry to ensure that the system is stable.
  • If you are still not satisfied with what CCleaner offers, you can go to the Tools tab to uninstall programs and applications directly, plug in the browser, analyze the drive, wipe the drive, and remove the restore point system. The free CCleaner does not have a user management option or a scheduled cleanup feature, but the free features of this tool are also very valuable.

6. MiniTool Partition Wizard

  • Link homepage: http://www.minitool.com/
  • The fifth application I would like to introduce to you in this article isMiniTool Partition Wizard.
  • We often have to split a drive into several different partitions, or have to clean a new partition on the drive to hold important documents and videos, so that if the operating system partition is affected, the data is still safe.
  • Microsoft has an integrated disk partitioning tool, but why the MiniTool Partition Wizard is mentioned here? The main reason is that it is very easy to use, very different from Microsoft’s cumbersome and confusing tools. Maybe that’s why the partitioning tool built on Windows is always a hidden feature, only suitable for users who understand this operating system only. Meanwhile, the MiniTool Partition Wizard has a very user-friendly interface, including advanced options for you. Plus, it’s free for personal use.

8. Ninite

  • Link: https://ninite.com/
  • The sixth application I would like to introduce to you in this article is Ninite. When you’re done installing the new operating system, the next thing you need to do is install a lot of applications on it, but the first set of applications may be the free applications you need. Ninite simplifies this process for you and saves you time. Ninite also helps you to avoid mistakes when visiting fake websites.
  • To get started, go to ninite.com and browse through the free apps it lists. You just select the application you need to install, then click “Get Your Ninite” button to download the file named ninite.exe. Once downloaded, just run the file so that the program automatically installs all the applications you have selected on the Ninite website. Very neat and convenient. Updating the free software version is simple, just pick and download the nineteen installation file.

9. Paper2PDF

  • Link: http://paper2pdf.net/
  • You may prefer the OCR character recognition software that comes with all-in-one printers, but these software is sometimes very basic and not very handy. Paper2PDF is a handy utility that reduces the time it takes to convert a PDF file into a single click.And this is the 7th application I would like to introduce to you in this article.
  • You can easily add multiple PDF pages to the back of the original PDF, and set PDF attachments automatically to outdate Outlook emails after the PDF has been created, saving you a lot of time and effort. The tool also has an option to open the PDF in the default PDF viewer of the system. Paper2PDF’s handwriting recognition function is also quite good. So this is a great tool for users or small businesses who often work with PDF scans and often have to email PDFs to partners, customers or archives and want to be able to search later.
  • 10. NeoRouter

  • Link homepage:http://neorouter.com/
  • The 8th app I would like to introduce to you in this article is NeoRouter. This is an interesting freeware, like a virtual network. You can install it on Raspberry Pi or even on a router, and it allows you to connect SSH / VNC (even WakeOnLAN packets) to computers on the network without setting up dynamic DNS. This is a very convenient tool if you want to make Raspberry Pi in distant places or difficult places to access the network.

11. Speccy

  • Link:http://www.piriform.com/speccy
  • The 9th application in this article is Speccy. Piriform is famous for its free tools, and Speccy adds that reputation. See Speccy as a health tool for your computer. Speccy opens the Summary tab, which tells you the basic operating system, CPU, RAM, motherboard, graphics card, hard drive, optical drive and audio. Each component has a detailed list. For example, RAM tabs detail memory usage and DRAM clocks. Or the Storage window shows you the speed of your hard drive and SMART parameters such as read error rates and spin-up startup times.
  • Speccy does not stop there. It has two sub-categories, Peripherals and Network, that give you details about which peripherals are connected to your PC or device, and lists Wi-Fi networks. The Network feature is also useful because it displays both external IP address and connection speed, saving you a lot of effort if you want to know the two. You can also capture images of these system parameters, posted online with a single URL path to share. Although it does not include any personal data, careful users can save data in XML format, plain text files, or printed information.
  • Like other Piriform free products, Speccy digs all the important information on your PC and organizes them in the most easily understandable, easy-to-share order.

12. Rufus

  • Link: https://rufus.akeo.ie/
  • The 10th application that I would like to introduce to you in this article is Rufus. This is a tool for creating bootable USB flash drives. This is a very useful tool for creating new operating systems such as Linux Mint or Ubuntu, or you may want to keep a Windows installation as a backup. Simply pointing to the Rufus ISO image file and pressing the “Start” button, the application will quickly complete the job as you wish.
  • Rufus can create a USB flash drive for booting with FreeDOS, which is fully command-line based, open-source, fully MS-DOS compatible. This feature is useful when performing low-level disk maintenance tasks, or with tools such as firmware updates that require direct access to the device.
  • Rufus is not just a bootable USB flash drive, it’s the fastest, at least in the opinion of many experts, compared to some other competing tools. Rufus can also create UEFI-compliant USB flash drives, which you can boot as soon as your PC or laptop does not have the “legacy” boot mode. Remember to turn off the Secure Boot function so that the system can boot from the USB you created with Rufus because it lacks the cryptographic signature.

11. Revo Uninstaller Free

Link:https://www.revouninstaller.com/

The 11th application that I would like to introduce to you in this article is Revo Uninstaller Free.

Revo Uninstaller Free is not the fastest app removal method, but it works very well. It creates a restore point, performs in-depth scanning and removes all traces of the program.

The Uninstaller tab includes a list of installed applications, their details (size, version, installation date and even the download site), and an option to uninstall or refresh the application. When you uninstall, first, Revo runs “parse” first, and creates a restore point for the system. Then, it opens the application’s default uninstaller and then runs the program that detects the files that have not been deleted, and then traces the entries in the Registry.

On the Tools tab, Autorun Manager stops the application from automatically launching, Junk Files Cleaner removes all unneeded files, and Browsers Cleaner cleans up temporary internet files and browser history.

Another interesting feature is the Hunter mode, which creates a fly-top icon on the desktop. You drag it through some software to remove the application, open its directory or stop it running automatically.

12. Sumatra PDF

Link:https://www.sumatrapdfreader.org

The 12th application that I would like to introduce to you is Sumatra PDF. Maybe Sumatra PDF just a little more beauty on the interface, this is really a great tool for users often work with PDF format. XPS, DjVu, CHM and comics support, Sumatra PDF file opening with a simple toolbar, including a set of common tools such as zoom, printing, cross the page and search. However, the power of this utility is located in the extensive shortcut key, help you view PDF files very easily.

You can also highlight and copy text and paste them into other applications very easily.In the past, Sumatra PDF has been known to “specialize” PDF formats with many charts, images or comics. If you’re bored with Adobe Reader, you can try this tool.

13. TeamViewer

Link:https://www.teamviewer.com

The 13th application that I would like to introduce to you in this article is TeamViewer. This is a remote access tool, which is free for non-commercial purposes, so it’s great for anyone who wants to switch between computers. Once you spend about two minutes signing up for a computer, you can connect to it from anywhere in the world, and use it remotely as if it was right in front of you. Because this is a remote hosted service, you do not even need to configure the firewall.

This utility also has many tools to make your work more smoothly. You can enlarge the desktop of the remote access machine to fit the current device screen, or change the resolution of the host to match the resolution of the machine you are using. If the connection is slow, you can reduce image quality to increase responsiveness. The sound of the remote system is also transmitted to your speakers, and you can even print the remote document directly to your printer. The utility also has a file transfer tool for you to transfer files directly between two computers. And if you’re concerned about others viewing your computer, you can turn off the computer screen remotely and disable the mouse and keyboard remotely.

Some of TeamViewer’s features are only available in Enterprise Edition and do not relate to features for individual users. However, it is more than enough for a great free tool, which gives you access to every computer.

Link:https://www.pcdecrapifier.com/

The most outstanding feature of PC Decrapifier is simplicity. With only 2MB, it quickly scans your PC and divides the applications into three categories: Recommended, Questionable, and Everything Else.And this is also the 14th application that I would like to introduce to you in this article.

When it does not have enough information to determine if it is bloatware (software pre-installed by the manufacturer when you buy it), it will transfer the application to Everything Else. Surprisingly, this tool lists the applications that you forget on your computer.

After checking which applications you want to uninstall, click the Remove Selected button and it will create a system restore point, and then remove the software. It’s done!

The 15th application that I would like to introduce to you is TestDisk. This is a great tool for diagnosing and repairing hard drive partitions alongside Speccy. It has a simple interface, including a command line interface.

TestDisk is an open source application, developed by CG Security, designed specifically to recover deleted partitions and / or non-bootable disks.

16. Wireshark

Link:https://www.wireshark.org/

The 16th application that I would like to introduce to you in this article is Wireshark. Wireshark is very good, as it is perfectly programmed, telling you exactly what’s going on on the network. Even so, Wireshark appears very much in network training programs because it is full of features related to network and network hardware. Many people wonder why a switch tells you to copy network packets from one port to another: that is, thanks to Wireshark, you can capture network data without any special other tools.

But Wireshark is actually a double – edged sword, as it is a free tool and a powerful tool for anyone curious about what to do on the internet. Hackers also use Wireshark to sneak a user’s packets.

17. WinDirStat

Link: https://windirstat.net/

The final application I would like to introduce to you in this article is WinDirStat.

If you wonder why your hard drive is running out of space so fast? You will need WinDirStat. This tool will review the entire drive, listing the size of each file and folder occupied by the hard drive. Take a few minutes to review, then this utility will show two sections. The upper part of the window is a regular directory tree, but adds a percent symbol, indicating exactly how each directory occupies the hard drive. Thanks to that information, you can easily look at folders that are too large to handle them.

In the window below, more intuitive, the tool displays a graph of the disk. Each file is represented by a square, colored code and can be zoomed to reflect the type and size of the associated file. If there is a file that is too large to be in a forgotten folder then you can see the file itself. Click to confirm the identity of the file and if not, click Delete to delete the file, clean up the hard drive space.
