How to Filter Out Files with Certain Extensions from OneDrive Sync in Windows 11

This article explains excluding files based on extension types when backing up with OneDrive in Windows 11.

The OneDrive app lets you sync files and folders on your computer with Microsoft Cloud. It allows you to access them anywhere on your mobile devices and other computers using the service.

You can automatically back up your essential folders (your Desktop, Documents, and Pictures folders) on your device with the OneDrive app.

While setting up a OneDrive process to back up your important files, you can exclude specific files based on extension types so they are not backed up to the OneDrive cloud.

You may want to exclude certain files from backup because they are unnecessary and take up valuable storage space. Additionally, backing up these files could slow the backup process and make it less efficient.

By excluding them, you ensure that your backups focus on the most essential data while saving time and resources.
