Windows 10


WinDirStat is a great tool to discover what is taking up most of the space on your disks. The treemap is an excellent feature. It shows all the content by visualizing it as colored rectangles. The larger the rectangle, the larger the file. This is a big boon to hunt down large files that you may want to remove to reclaim lots of disk space in one go. The classic tree view is also present, with details about the files. Next to that there is an extension list. Another boon for file management. It allows you to explore files by extension. For example, you could select an extension that matches video files and it will show where they are and how much space they are using. All the fields interact. Click on a large rectangle in the treemap and the tree view will mark the same file or folder. In this way you can hunt down the specific file on the disk through the folder structure.
