DiskTreeSize is a disk space analyzer built for macOS. It helps you understand exactly which files and folders are taking up space on your Mac. When macOS shows a huge “System Data” section but does not clearly explain what is inside, DiskTreeSize helps break down hidden storage usage from caches, backups, developer files, downloads, model files, app data, and large folders. Key highlights: Understand what is inside System Data Quickly identify common storage sources such as caches, backups, developer folders, app data, and other large local files. File tree and visual maps working together Browse disk usage by folder hierarchy, or use visual maps to spot the biggest space consumers at a glance. Four visualization modes Explore your storage with Treemap, Galaxy, 2.5D, and City views. Allocated size and logical size Switch between actual disk usage and logical file size for more accurate analysis. Find large files and folders faster Useful for checking Downloads, Xcode DerivedData, iPhone backups, model files, caches, and other common storage-heavy locations. Local scan, privacy first Scan results stay on your Mac. DiskTreeSize does not upload your file paths or disk data. Export reports Export scan results as CSV or JSON for archiving, sharing, or further analysis. DiskTreeSize is designed for users who want to clean up Mac storage, analyze System Data, find large files, inspect cache usage, and understand where disk space is going.
