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

Have used GrandPerspective many times over the years to help carve out free disk space in a pinch.
The interface has changed little over the years, which speaks to the quality of the original design: fast, solid, and straightforward. GrandPerspective does one important thing and does it well.
no Bells and whistles - it Just Works!
I’ve used GP for a number of years. I’ve bought other similar apps in the past, and keep coming back to GP. I’m glad I can support the developer. Keep up the good work, for a something that does the job.
This is one of those apps I’ve been using for years to keep an eye on where free space is going. Easily worth a few bucks. Developer has always been very responsive.
