I am using Office 2003 on Windows XP.

Periodically I copy oulook.ps to an external hard drive as a backup.

When I try to do it now, I get the message "Cannot copy outlook: The
process cannot access the file because another process has locked a
portion of the file."

I have rebooted, but that doesn't fix the problem.

By the way, the outlook.ps is large, slightly over 4 GB.

Any suggestions?

Thanks,
