SyncWing keeps folders identical across your drives — and with OneDrive, Google Drive, Dropbox or your own server. Every replaced or deleted file is archived first, automatically.
Windows 10 / 11 · 30-day full trial · no admin rights · works offline
Designed so a mistake can never destroy data. Configure it once, then forget it exists — SyncWing watches both folders and keeps its own history of everything it changes.
Replaced and deleted files go to a timestamped version archive before they disappear. Browse and restore any version with one click.
Edit on either side — changes travel both directions automatically. Conflicts keep both versions instead of guessing a winner.
OneDrive, Google Drive, Dropbox, SFTP or WebDAV — or plain local folders. No accounts with us, no cloud of ours.
Hidden identity markers abort the sync if a different drive shows up under the same letter — it never merges the wrong disk.
If more than 100 deletions appear in one run, the sync stops and asks. Ransomware-style wipe-outs don't propagate.
No telemetry, no sign-up, no internet needed for local sync. Server passwords are stored obscured, never in plain text.
Three steps. The first sync is always a safe merge that never deletes anything.
A folder on your external drive and its match in the backup — a local folder, a cloud service, or your own server. Add as many pairs as you like.
Preview shows exactly what would happen, read-only. The first sync merges both sides: newer files win, nothing is deleted.
SyncWing syncs about eight seconds after changes settle, plus a reconciliation pass every 20 minutes. Ejected drive? It resumes on its own when the drive returns.
| Event | What SyncWing does |
|---|---|
| File edited on one side | Copied to the other side — old version archived first |
| File deleted | Deletion syncs, but the deleted copy is archived — recoverable |
| File edited on both sides | Newer version wins — the loser is kept as *.conflict, never erased |
| File renamed | Rename is detected — no duplicate copies |
| Wrong drive at the same letter | Sync aborts — identity markers don't match |
| Excel file currently open | Retried automatically, picked up on the next pass |
No subscription. Every license includes free updates within the major version and works offline forever.
30-day full trial first — no credit card needed. Your license works offline and never expires.
The questions buyers actually ask.
Yes — all features, no limits, for 30 days. The only difference after the trial ends is that syncing pauses until you enter a license key. Your folders and version history are never touched.
Never. Local sync never touches the internet at all. Cloud sync connects directly from your PC to your own OneDrive, Google Drive, Dropbox, or server. SyncWing has no servers that see your files.
Email support with the name you bought it with and we'll re-issue it. Activation works fully offline — you only need internet to download the app.
Yes — licenses follow you, not the machine. Email us when you switch and we'll free the seat.
OneDrive syncs to Microsoft's cloud only — and a mistake syncs too. FreeFileSync is a good manual tool but has no automatic monitoring, no version archive, and no drive-swap protection. SyncWing is set-and-forget with safety rails.
Deletions propagate so both sides stay in sync, but every deleted file lands in the version archive first. To truly lose a file you would have to delete it twice — once from your folders and once from the archive.
