WinDirStat

WinDirStat is a program that provides detailed information about the occupancy of all or selected disks/folders. It displays the size of all files and folders and sorts them in descending order. The program also shows statistical information about the number of files of different types on the hard disk.

The program scans all or selected hard drives or individual folders and lists all files and folders/subfolders. The list is sorted by item size and provides information about the size, number of files and subfolders in a folder, last modified date, attributes, etc. On the sidebar, WinDirStat displays a list of file types on the disk or in the folder, the number of files of each type, their total size, description and other information.

Interactive disk map in WinDirStat shows all files and folders stored on it in video blocks. By clicking on a block you can see its size, location and other information.
