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:
• Navigate using mouse or keyboard
• Quickly search for files by name
• 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:
• Refresh or rescan 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
• Export scan results as image or text
Snappy and responsive GUI:
• Optimized drawing of views
• Drawing and scanning are carried out in background threads
• Animated changes to view content
Furthermore:
• Configurable user preferences
• Small memory and disk footprint
• Extensive help documentation

super informative, functional and clear

Everyone talks about Daisy Disk, but I find that confusing ,irritating and unclear (I have it installed). On the other hand, this works great for me, making space hogs easy to see in relation to everything else without always changing views in hard to back out of ways, but it’s probably just me. Being able to delete stuff directly is great, but you need to be careful you understand what you’re doing.
Incredibly useful app, I've used it for years

This should be in everyone's toolbox. I've used free versions of this for literally years and years and when I saw it was available on the App Store, I immediately paid for it so I could support the developer.The developer is asking next to nothing for a tool that is super-useful, I highly recommend it. Great stuff.
Brilliant

Excellent app for figuring out where all the space on your harddrive has gone. Quick to scan and the result is very easy to understand and take action on.
Beautiful on the inside

Despite this app’s need for a visual refresh, I’ve found it incredibly useful for getting a visual overview of where the storage space on my Mac is going which macOS’s built-in tools simply cannot provide.
