This file is in use by another application or user.
This error is commonly encountered when a read lock is set on the file that you are attempting to open. Possible reasons for this:
Another user has the file open, either on the same computer that you are using, or on another computer.
Word crashed at some point in the past and left a read lock on the file.
Another application has an exclusive lock on the file, preventing Word from opening the file.
A custom application is running and has opened this file (possibly on another user's computer). It may have opened the file using an incorrect method.
To correct this problem, close all applications, restart Word and try to open this file again. If this does not work, examine the properties of the file to determine if someone else has it open. Occasionally a phantom process (dead or disassociated program) may have a lock on the file, and the only means of clearing it is to restart your computer.
