What to do first
Check OneDrive on the web and the signed-in account first, then inspect the OneDrive folder, status icons, and backup settings before restoring or moving files.
OneDrive and cloud files
Files missing from a OneDrive folder may be online-only, under a different account, filtered by Files On-Demand, or still waiting to sync.
Quick answer
Check OneDrive on the web and the signed-in account first, then inspect the OneDrive folder, status icons, and backup settings before restoring or moving files.
Why it happens
OneDrive can show different content when the wrong account is signed in, a folder is not selected for sync, or Files On-Demand has not downloaded a local copy.
Step by step
Safety note
Protect important files before resets, driver removal, account changes, or recovery operations. If the symptom points to hardware, repeated software changes can make diagnosis harder.
The folder may not be selected for sync, Files On-Demand may be in use, or the PC may be signed into a different account.
They remain in OneDrive online but may not be stored locally. Download or mark important files for offline use before traveling or making major changes.
