Trace Documents being moved from Pc to Flashdrive

I have a new client that just terminated an employee. Right after that event, they checked the employee's Pc and found company documents missing from his stand alone peer to peer Pc. They never took any backups.

I installed Recuva and ran a full system scan for deleted files. The only files found were from a few months ago and there were only a few files per day deleted at that time. Nothing that would point to a mass deletion which is what I was looking for.

I suspect he moved all documents to a USB flash drive and took it with him.

Is there any way to track this down in Windows Logs?

No, there isn't. This would require settings for file auditing in place already before the copying.

"Moving" a file to a different drive is basically just a copy + delete function. First the OS copies the file to the destination, then deletes it from the source location. So undelete programs will recover "moved" files, assuming they haven't been overwritten.

You may want to try "Previous Versions" built into Windows 7 to recover the files. See instructions here:

Another possibility is that they were moved elsewhere on the same drive and/or hidden. They wouldn't show up as deleted then. You can use this tool to look for hidden files:

For moved files, search the whole drive:

Other possibilities are that the files were never saved on the PC's drive: the user may have created and kept everything on a USB drive in order to work on the files at home.  Or, if the user was malicious, used a file wiping program to "shred" or overwrite the files on the disk, making undelete impossible.

Good reasoning for using a domain.. during the termination interview the user account is disabled in AD
