Description:

GrandPerspective is a small utility application 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.

Disk usage is visualised using tree maps. Each file is shown as a rectangle with an area proportional to the file's size. Files in the same folder appear together.

Configurable display of views:
• Color files by their: name, extension, file type, parent folder, top folder, level in the folder hierarchy, creation time, modification time, or last access time
• Choice of color palettes
• Configurable mapping by file type
• Optionally view package contents
• Optionally view the entire volume

Convenient navigation of views:
• Traverse up and down the folder hierarchy
• Select files and folders in the view
• Preview files using Quick Look
• Reveal files and folders in Finder
• Delete files and folders from the view

Filter files and folders:
• Construct filter tests based an item's name, path, size, file type, hard-link status, and package status
• Filters and filter tests are automatically stored in the user preferences

Use these filters to:
• Mask files in the view
• Filter files from the view
• Exclude files and folders when scanning a disk

Multiple view support:
• Re-scan a view to compare results before and after clean-up
• Twin or duplicate a view for different displays of the same data

Support for hard-linked files and folders:
• Analyse Time Machine back-ups

Save results of disk scanning operations:
• Save, reload and view again at any time
• Save images of views

Snappy and responsive GUI:
• Optimized drawing of views
• Drawing and scanning are carried out in background threads

Furthermore:
• Configurable user preferences
• Small memory and disk footprint
• Extensive help documentation

Excellent tool for understanding disk usage - I’ve been using the free version of this app for years. Once I found it in the Mac App Store I immediately bought it to support the author. This app gives you a wonderful visual understanding of what’s using your hard disk’s space. Once your folder/disk is scanned you can move your cursor over a block and the file name appears at the bottom of the window. If you want to go to that file, click the block then click the ‘Reveal’ button at the top. If you want to actually launch (open) the file, click the ‘Open’ button. This app is a real gem!
