SharePoint 2010 - Document Library (checked out documents not visible to anyone)
Issue When trying to remove folders in a document library, it appears that no files exist in the folder, yet you receive an error saying the files have not been checked in. Workaround Go to the Document Library Settings, select Manage files which have no checked in version, then select Take Ownership of Selection. This will allow you to check in the files that were missing, and remove that folder.
