You could track changes on a shared workbook, but you'd still need the file.

I have deleted an important file that wasn't supposed to be on my computer in

anyone had accessed it before I did. Is there any way to find out if anyone
has accessed a document even after you've deleted that document? Maybe some
sort of a document log?
