Let us face the facts: too many users delete things by mistake and do not back up regularly or properly. Or criminals delete files on purpose. In such criminal cases, you often have only minutes between the time the police knock on the door, and the suspect answers the door. This is more than enough time for suspects to delete files on their computer and try to delete or hide incriminating evidence. So what can we do to recover deleted files? Can anything be done to prevent such deletions, especially in cases when this is done accidentally?
