Cleaning Up Files
By default, File History saves your backed-up files forever. In many cases, you will want to keep all versions of your files, but if you have files that change often, keeping all versions might mean that your backups use more disk space than you would like. Fortunately, you can clean up backed-up files so that you can free disk space on your backup drive.
Performing a Clean Up
When you clean up file versions, you can specify to clean up files older than a certain time frame, or you can clean up all versions except the most recent version. In no cases will cleaning file versions remove the latest version of a file.
From the Advanced Settings dialog in File History, tap Clean Up Versions.
- Select an option from the Delete Files drop-down. By default, a cleanup will remove all files older than one year, but you can modify that as desired.
Tap Clean Up to delete the file versions in the backup as per your selection.
