I have never seen anything like that. The folder wasnt even on the Windows drive, and it was the only folder hit like that including all of it s sub folders.
When you right click on the main folder and go to properties does it show size is at 0 bytes?
Are there any kind of cleaner tools you run at all? Only reason why I ask is I want to cover all bases and I want to check any logs they might have made.
If the files where deleted and now even a raw or delete recovery can see them then the only way that could of happened is if the data gets over written on the drive, which any kind of cleaner with a data wipe option would do.
I know it is a long shot, but data just doesnt disappear. Well ok it can, but normally like one file that might have been on a bad sector. Not a single folder and all of its sub folders. Something targeted that folder and wiped it. I want to find out what.
