Drive Atlas
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.
