Strange Folder In My Trash

I haven't used my MacBook since last night, but I know my roommate has...

Today, well about 10 minutes ago when I got on, I noticed there was something in my trash.

The folder that is in there is named "501.175104320"

Does anyone know what that is?

Did you open it to see what it was?

Yes, it has names like annex.db, filetoken.db, fonts.db, qdfams.db, etc... looks like more apps or programs in the folder.

Doesn't appear to be anything crucial to me. Sounds like your buddy may have been trying to utilize some Windows programs or something of that sort. I would just empty the folder from the Trash and be done with it.
