You can take ownership of files and folders from other users.
You may need to do this if someone who owned a file or folder has left your company and you need to take responsibility for it.
Note: You need to be a Site Manager or have permission to delete a file or folder to become its owner, see User roles and permissions.
Click on a file to open the file preview.
Tip: If you're taking ownership of a folder you need to hover over it then select View Details.
Click Become Owner and select OK.
You now have full ownership rights of the file / folder.
