If you need more space, you can change the file back to online only. Just right-click the file and select “Free up space.”
Files that you mark as "Always keep on this device" have the green circle with the white check mark.
These always available files download to your device and take up space, but they’re always there for you even when you’re offline.
OneDrive will show a padlock icon next to the sync status if the file or folder has settings which prevent it from syncing.
