File History can save versions of personal files to an external drive or network location, but Microsoft notes it primarily covers libraries and common folders. A project directory elsewhere may be invisible to the backup until added to a library. The right setup first lists important folders, then includes them deliberately, checks the drive and restores a test file. A backup status without a restore test can hide missing paths or a disconnected disk.
Before you start
Use an external drive with enough capacity and a separate physical location when it is disconnected. Identify files in Documents, Pictures, Desktop and any custom work folders. Do not rely on File History to protect installed programs or the Windows operating system. If the PC has a history of malware, keep the backup disconnected except during planned backups.Do it step by step
- Connect the backup drive and open Control Panel > System and Security > File History. Choose Select drive if Windows picked the wrong disk.
- Turn on File History and let the initial backup finish. Note the last successful run and the drive letter or network path.
- For a custom folder outside default libraries, add it to an appropriate library using File Explorer's Include in library option, following Microsoft's documented method.
- Create a harmless test document in the custom folder, change it after one backup interval and confirm multiple versions are available.
- Use the restore interface to open an older version and restore a copy to another location. Compare its contents with the expected earlier state.
- Set a recurring reminder to connect the drive, check backup status and replace a failing drive. Keep another copy for critical data in case the backup disk is lost.
