OneDrive .tmp.driveupload & Sync Temp Files

Bottom Line: It is 100% safe to delete .tmp.driveupload files and clear the OneDrive sync cache. Doing so will not delete your actual cloud files saved on OneDrive.

What are .tmp.driveupload Files?

Located inside your OneDrive folder (or hidden in %LocalAppData%\Microsoft\OneDrive\logs), .tmp.driveupload files are temporary chunk files created by the Microsoft OneDrive sync client.

When OneDrive uploads large files, videos, or zip archives to the cloud, it splits them into smaller .tmp.driveupload temporary chunks. If an internet disconnection or crash occurs during sync, these temp files can get stuck permanently on your SSD.

Can You Delete .tmp.driveupload Files?

✅ Yes, it is completely safe to delete.

• No cloud data loss: Files that have already synced to OneDrive online are 100% safe.
• Fixes sync loops: Deleting orphaned sync temp files fixes OneDrive status stuck on “Processing 1 change” or “Sync pending”.
