DirStat
DirStat is a Mac disk usage analyzer that helps you inspect folders and files to understand what is taking up storage space.
What is DirStat?
DirStat is a native Mac utility for exploring disk usage and identifying folders or files that consume large amounts of storage. It is intended for users who want a clearer view of space usage than Finder typically provides, whether they are cleaning up a crowded startup disk, checking external drives, or investigating unexpectedly large directories. Apps in this category usually present storage information visually so you can compare locations quickly and drill down into subfolders to find the biggest items. That makes them useful for routine maintenance, developer workspaces, media libraries, downloads, and other storage-heavy workflows. DirStat fits best as a focused system utility for everyday Mac storage inspection and cleanup planning.
Key features

Safety overview
Status: Unknown
DirStat is a disk-analysis utility category, which is ordinarily low risk, but this specific app entry needs extra care because the product identity is not fully established from the available metadata. Before trusting it with full-disk access or using any file-deletion features, confirm that the app name, developer name, signing details, and bundle ID com.macdirstat.app match what you expected to install. If the app asks for access to your files or removable drives, that request is consistent with a disk usage analyzer, but you should grant only the access you intend to scan.
Recommendation: Keep DirStat only if you installed it intentionally and its developer and signing details match your source. If you do not recognize it, open the app's Get Info window or System Settings security details, verify where it came from, and remove it if you cannot confirm its origin or no longer need a disk usage tool.
