You can update files by checking them out and then checking them back in. When you check out a file, the file is locked, and no other user will be able to upload a newer version (overwrite the file). When you check in the file, you will be prompted to upload a newer version to replace the original file. The file, after being checked in, will be available for other users to check out again. If you do not want to upload a new version, you can undo the checkout, if you are the person who checked the file out. See Cancel a Check Out below for who else can.
Note: To enable or disable file updating, enable or disable Document Control in the Control Panel.
Only the person who checked the file out can cancel it, or a site administrator. Space administrators and space moderators do not see the option, even in their own space, so being able to manage everything else there is no help here.
If the person who checked the file out has left or is unavailable, ask a site administrator to clear it. Until it is cleared the file stays checked out, and it cannot be deleted in that state.
You can edit Microsoft Office files in Office Online. Users can work on the same document simultaneously. See Update File in Office Online.
