GrandPerspective is a small utility application for Mac OS X that graphically shows the disk usage within a file system.

It can help you to manage your disk, as you can easily spot which files and folders take up the most space.

It uses a so-called tree map for visualisation. Each file is shown as a rectangle with an area proportional to the file's size. Files in the same folder appear together, but their placement is otherwise arbitrary.

What's New:

Bug fixes:
- Fixed "silly typo" bug that caused crashes when scanning.
- Failures of FSRefMakePath do not abort scanning anymore, but are
handled gracefully instead.
