Cut & Paster lost files on network share

Dear All,

I am wondering if you could help, yesterday some of our
users used the "cut and paste" option to copy some files
up a few levels in the same directory structure on a
Win2k server....

Instead of letting us do the users stated
that "something" happened and some of the folders are
missing, i have not got auditing set up so is there a way
to track down how or what has happended to the them??

Thanks

Keith
