If you have the cooperation of the other program then this can be fairly simple. If you do not have the cooperation of the other program than this can be difficult and may require enhanced access permissions to the operating system table of open files.

There are mechanisms that are not so bad that can notify you when a file is being changed, but the mechanisms to tell you when all other processes have closed the file are lacking.

The details are going to depend upon the operating system you are using.

If you can get the cooperation of the other program then you are much much better off.
