Drive Atlas vs TreeSize

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.

TreeSize analyzes files and folders to show how storage is used on Windows desktop systems. Scans can cover local drives, network shares, cloud storage, USB drives, SD cards, and external hard drives; treemap views and file-type breakdowns help present the results. Depending on edition, results can be exported to PDF, Excel, CSV, HTML, or SQLite. Professional adds server scanning, command-line parameters, scheduled scans, and automated reporting. Other listed tools include deleting, moving, bulk renaming, archiving, duplicate finding, and deduplication. TreeSize Free is for private, non-commercial use on Windows desktop and cannot be used on Windows Servers. The editions run on Windows Desktop and operate on-premise; the maker says data does not leave the computer or site and is not shared with third parties. Personal and Professional have 14-day free trials, while SpaceObServer Enterprise has a 45-day trial. Annual prices listed include 20.40 € per user for Personal and from 40.80 € per user for Professional. The Free plan is listed at free.
