Anybody have an informed opinion on how long it might take an fbi expert to recover deleted files off a computer?
To identify how many files were deleted and what they were is a matter of minutes. To understand its content can take forever. A file is not like a sheet of paper anybody can readily read. To understand what temporary files of certain programs do contain is a little more complicated. If you want to track back remainders of windows virtual memory file sectors to certain programms, you need to be a real nerd, but may find very conclusive content. There is a good chance that the programm with the highest memory demand recently running was the flight simulator, so there should be a lot of not yet overwritten pieces of virtual memory on that computers hard drive. Windows is not at all optimized for privacy and security...
