File History stopped working: how to fix it

File History is the free backup built into Windows. It works well once set up, but it tends to stop silently: the drive changes letter, fills up, or a Windows update turns the feature off, and nobody notices until it is needed.

Signs this guide is for you

• The message "Reconnect your drive" appears or the feature says it is turned off.
• The date of the last copy is weeks or months ago.
• Folders outside the Libraries don't appear when restoring.
• Windows 11 doesn't show File History in Settings.

Why it happens

• The external drive changed letter or was formatted, and Windows no longer recognizes the destination.
• The destination filled up and old versions are not being removed.
• On Windows 11, the feature only appears through Control Panel, and folders outside the Libraries must be added by hand.
• Files with very long paths or open during the copy are skipped.

How to do it, step by step

1. Open Control Panel, go to System and Security, then File History.
2. If the drive is not found, plug in the drive, click Select drive and choose the disk again. The old copies are still there.
3. If the drive is full, in Advanced settings shorten how long versions are kept or click Clean up versions.
4. Click Run now and wait for it to finish; then, in Restore personal files, check that the right folders appear.
5. On Windows 11, to include a folder that doesn't appear, add it to a Library or use another backup tool.
6. If File History keeps stopping, consider a program that warns about failures and tests restores, such as Neural Backup's Free plan.

So it doesn't happen again

• Write down the day you last checked the backup.
• Use a drive only for backup, with no other files.
• Keep a second copy away from home.

Menu names may vary with your version of Windows. If a file is already missing, do not write anything to the drive where it was before trying to recover it.

No backup is an absolute guarantee: a destination can fail at the same time as the computer, and files that never made it into a backup cannot be restored. That is why the app verifies copies, tests restores and always recommends two destinations.
