DiskScope vs Drive Atlas

DiskScope is a free, open-source desktop app for analyzing disk usage, finding files, and uninstalling applications. It scans files, folders, and apps in parallel, showing results in a sortable table, tree explorer, and zoomable treemap. Views include application sizes and file-type breakdowns. Fuzzy search filters by type, extension, size, and modified date and is designed to remain smooth beyond 100,000 rows. DiskScope reports actual on-disk usage, including sparse and compressed files. Deleted items move to the Recycle Bin; emptying it permanently clears contents after confirmation. On Windows, the Applications tab shows an installed program’s command before launching its native uninstaller. Disk analysis and search work on Windows, Linux, and macOS. Downloads list Windows 10/11 x64, macOS 12 or later, and Linux x64 builds. The macOS and Linux builds are marked experimental and not tested yet. The app runs locally with no telemetry, according to its maker, and checks for signed updates.

Drive Atlas catalogs drives so users can search for files even when the drive containing them is unplugged. Search by file name, project, or date range, then see which drive holds a file and where that drive is located. A treemap shows drive contents, including offline drives. The app can find files that exist in only one place, verify backup copies by hashing both sides, and check duplicate groups byte for byte before moving selected copies to the Recycle Bin. Drive health tools benchmark drives over time and can list unique files on a failing drive for evacuation. It also analyzes numbered image sequences for timelapse interval and steadiness, and creates printable QR labels with drive summaries. The maker says the app makes zero network connections and does not interpret image content or use AI. Drive Atlas runs on Windows and Linux. The free plan covers the first two drives and includes all features, with no card or timer; the one-time license is 20.00 USD for all drives.
