GrandPerspective: Free Open Source Disk Space Analyzer for macOS
Discover how GrandPerspective helps you visualize and manage your disk space on macOS, providing an intuitive treemap layout to quickly identify files and folders taking up space.
What is GrandPerspective?
GrandPerspective is a free and open source disk space analyzer application designed specifically for the macOS operating system. It provides users with a graphical visualization of what files and folders are taking up space on their hard drives.
One of the key features of GrandPerspective is its use of treemap layouts. It draws nested rectangles representing folders and files on the hard drive. The sizes of the rectangles are proportional to the amount of disk space the corresponding file or folder occupies. This allows users to get a visual sense of disk usage at a glance.
When GrandPerspective scans a volume, it displays the treemap visualization with interactive capabilities. Users can click on any rectangle to zoom in and see subfolders and files under that folder. Color coding indicates different file types. Users can search for specific files and hover over rectangles to see more details and file paths.
This visualization and interactivity enables users to easily identify what folders and file types are occupying large amounts of space. Users can quickly spot usage patterns and outliers and prioritize areas to free up disk space by deleting unused files.
Some key uses and features include:
- Seeing the distribution of file types on a hard drive and spotting outliers taking up excess space
- Finding large hidden files cluttering up space that users were unaware of
- Identifying good candidates for compression to free up space
- Comparing disk usage before and after adding/deleting files
- Supporting standard macOS volumes, including mounted drives, external drives, network volumes, DMG files and disk images
- Saving treemaps as images to document disk usage over time
With its focus on macOS, intuitive treemap visualizations and interactive features, GrandPerspective is an excellent disk usage analysis tool for mac users looking to understand and reclaim hard drive space.
