GrandPerspective vs TreeSize Free
Side-by-side comparison of features, pricing, ratings, and alternatives.
GrandPerspective is a free macOS utility that scans a folder or volume and displays disk usage as a treemap, where each file is drawn as a rectangle sized proportionally to how much space it consumes. This makes it fast to spot the largest files and folders visually rather than digging through nested Finder windows. Released under the GNU General Public License, GrandPerspective supports multiple color-mapping schemes (by file type, size, or modification date), filtering and search, and can compare or combine multiple scans. It is distributed for free from SourceForge, with an optional paid copy on the Mac App Store for users who prefer automatic updates and app-review verification.
TreeSize Free, by JAM Software, is a free disk space analyzer for Windows that shows which folders and files are consuming storage. It presents a treemap visualization of disk usage and can generate PDF reports, making it easy to spot what is taking up space on a drive.
