i saw a news program about the 14 year old girl in utah who was kidnapped a few weeks ago, and in the story, it was noted that the FBI had seized about 20 computers of family members and near-by neighbors.
anyway, the "expert" guest was saying that the FBI techno-nerds have a way of recovering deleted internet files that one has downloaded on their computer. he kept going on and on about how the average computer user knows nothing of this, that only experts know how to dig in and recover info.
i was under the impression that downloaded internet files could be removed by deleting cookies, temp files and temporary internet files, as well as clearing the history and emptying the recycle bin. am i wrong about this?
does the hard drive still contain info on sites one has visited even after deleting the contents of the above mentioned folders? if so, how much space does this take up?
