I had 'compact on close' checked in my database, but had never experienced this problem before. Today, about 10 minutes ago when I closed the file, I got a message that 'access can't delete the file....', and on clicking 'ok', my database disappeared. It isn't even in the recycle bin. I found this article http://allenbrowne.com/bug-DeleteOnCompact.html which is very depressing if true; I am hoping that somebody might know that the database simply gets moved or something, of if there is a way to retrieve the file. Thanks.
