What is Disk Space Analyzer?
Disk Space Analyzer is a native Mac storage analysis utility that helps users understand what is taking up space on internal drives, external disks, network volumes, and selected folders. It presents scan results in a visual sunburst map and folder outline, making it easier to spot large files, bulky folders, and old content that may no longer be needed. The app is designed for people who want a clearer view of disk usage before moving files, copying data to another drive, or sending items to the Trash. It also supports file previews and file details during review, which can help with manual cleanup and organization. On macOS, it fits common workflows such as checking a full startup disk, reviewing external storage, and inspecting specific directories before reclaiming space.

Safety overview
Status: Mostly safe
This is a legitimate disk analysis utility for macOS. Full Disk Access may be requested so the app can scan protected folders, which is consistent with its purpose. Because the app can move, copy, and send files to the Trash, review selected items carefully before making changes, especially in personal or work folders.
Recommendation: Keep Disk Space Analyzer if you use it to inspect storage, find large files, or manage disk cleanup on your Mac. If you no longer use it, removing the app is usually reasonable; just expect to lose its saved settings and any convenience it provides for future storage reviews.
