Snooping

This is when someone looks through your files in the hopes of finding something interesting whether it is electronic or on paper.

In the case of physical snooping people might inspect your dumpster, recycling bins, or even your file cabinets; they can look under your keyboard for post-It-notes, or look for scraps of paper tracked to your bulletin board.

Computer snooping on the other hand, involves someone searching through your electronic files trying to find something interesting.
