What have you tried? Often, this happens when a linked file is open...perhaps at the hands of another user across a network where you can't see. If that's not the case, and you're sure you don't have it open, it's still possible your system just thinks it's open. Reboot the computer and try again.
i check the name of the link and carpets, nothing works. I think is only a problem of one document… 388 link one by one … i don't think so
This is often caused by a special character in a file or folder name, typically a slash or asterisk, or by an extremely long path to the file.
