GrandPerspective

GrandPerspective is a utility application for Mac OS X that provides a graphical representation of disk usage within a file system. This valuable tool assists in hard drive management as it allows you to easily identify which files and folders are taking up the most space. To visualize disk space, GrandPerspective uses what is called a treemap. Each file is represented as a rectangle, with the area of the rectangle proportional to the file's size. Files within the same folder are grouped together, but their arrangement is otherwise arbitrary.

• Visualization of disk usage through treemaps
• Variety of color mapping schemes and color palettes
• Configurable mapping by file type
• Optional package content viewer
• Full volume display (optional)

Aside from file visualization, GrandPerspective offers user-friendly navigation within views. You can move up and down through the folder hierarchy and select files and folders in the view. It's also possible to reveal files and folders in Finder and remove them from the view. File and folder filters are also supported for a more customized experience.

An outstanding feature of GrandPerspective is its support for multiple views. You can re-scan a view to compare results pre and post-cleanup or duplicate a view for different displays of the same data. The software also allows you to save the results of disk scanning operations and images of views.
