Although the storage analyzer of Windows 10 can be used for the same purpose but it will only show a summary of each category for example, it will show you how much size temporary files are there on the drive and how much size system files are there. The below mentioned tools will help you identify the problems in filesystem size visually.

1- WinDirStat

WinDirStat is a free tool that helps you in visualizing the clear view of your File System, so that you can easily see the folder size of each folder. And it shows the total disk size of your Hard Drive. Its file size is very small. And the tool is a portable version, so it will not use any of your System resources or won’t run in the background. You need to select the drive which you want to view, then all its folders with size will be shown to you.

When it will finish gathering the files, the tool will show each file with different colored areas for every file type.

You can open any other drive too, by going to “File” menu and then click on “Open”.

2- Space Sniffer

Space Sniffer is another portable tool to show you the File System visually. All file types will separately be visible, easily with the file size. A graphical view shows the rectangles for each file.
