DiskGraph is an application (or website) designed to help users better understand and visualize their disk usage. It provides a graphical representation of disk space usage in percentage and bar graph form, allowing users to quickly identify which folders and files are consuming the most disk space. It also provides detailed information about the files and folders, such as size, type, and other properties, allowing users to make informed decisions on which files to keep and which to delete. DiskGraph can also be used to identify potential problems with disk usage, such as fragmentation or large files that could be causing performance issues. Additionally, DiskGraph can be used to help users determine how much free space is available on a given drive, allowing them to plan ahead when it comes to storing data.
Discontinued The program seems to be no longer updated. The latest version, 2.13, released in July 2012, is fully functional and can still be downloaded from the official website.
