This is one that will come in very handy if you have users who upload documents via Explorer, but you have required metadata in the library.
In each library, there is a link under Permissions and Management in the Document Library Settings, “Manage files which have no checked in version” (In SP2007, the link is ‘Manage checked out files’.)
When you click on the link, you are taken to a list of documents that have been uploaded by other users, but for one reason or another have never been checked in. Usually that reason is the user dumped the documents in the library but never provided that required metadata.
So, let’s say, for instance, that a user has uploaded a number of documents, but never completed the process by providing the required metadata. Maybe they were in a hurry to go on vacation. Of course, once they are on vacation, those documents don’t appear to be in the library, and the user doesn’t have access to get to the documents to check them in, or perhaps they are completely out of contact. (Because that never happens.)
In that case, someone with Full Control rights on the library can be instructed where to find the link, and then how to take ownership of the documents, so they can provide the metadata and get the documents checked in for use.
In my opinion, it is important to have an end-user with appropriate domain knowledge fill in the metadata rather than an administrator, for several reasons. First, admins should be empowering end-users on general principle. This frees the administrator to handle issues with larger implications. Second, the administrator is likely to not have sufficient domain knowledge to fill in the metadata correctly.
