GrandPerspective

GrandPerspective is a highly useful utility application designed for Mac OS X that allows users to visualize the disk usage within a file system. With this software, you can easily manage your storage space and identify files and folders that are taking up excessive amounts of space.

This tool employs a useful tree map for data visualization purposes, whereby each file is displayed as a rectangle with an area relative to its size. Although, files in the same folder appear together, their positioning is otherwise arbitrary.

The software comes equipped with a range of features such as configurable display of views, choice of color mapping schemes, configurable mapping by file type, and the ability to view package contents and the entire volume. Moreover, it also boasts convenient navigation and filtering of views that help users to traverse the folder hierarchy, select and delete files, and reveal files and folders in the Finder.

This software also supports hard-linked files and folders, can analyze Time Machine backups, provides memory and disk footprint, is fully internationalized, and has extensive help documentation. It is available as a Universal Binary and is designed to support multiple views that allow you to compare the results of clean-up and save images for later retrieval.

Overall, GrandPerspective is an excellent tool for managing and monitoring storage space on Mac OS X, with a snappy and responsive GUI, configurable user preferences, and the ability to save results of disk scanning operations.
