By drawing files and folders as nested rectangles, DiskVision shows, visually, how much space each file and folder consumes. This makes it easy to track down files, folders, and applications that are wasting space.

Features:
- Displays file and folder sizes in easy-to-understand nested rectangles
- Displays sizes by actual size, used size, wasted size, or equal size
- Provides detailed information on individual files and folders
- Supports deleting, moving, and renaming files and folders and creating folders
- Includes palette editor for changing display colors
