The common problem with deleting files is accidental removal of information that later proves to be important. One way to deal with this is to back up files regularly. Erroneously deleted files may then be found in archives.
Another technique often used is not to delete files instantly, but to move them to a temporary directory whose contents can then be deleted at will. This is how the “recycle bin” or “trash can” works. Microsoft Windows and Apple’s Mac OS X both employ this strategy.
In MS-DOS, one can use the undelete command. In MS-DOS the “deleted” files are not really deleted, but only marked as deleted, so that they can be undeleted during some time. This is possible until the disk space used by them is eventually taken up by other files.
Another precautionary measure is to mark important files as read-only. Many operating systems will warn the user trying to delete such files. Where file system permissions exist, “ordinary” users are only able to delete their own files, preventing the erasure of other people’s work or critical system files. Despite these precautionary measures, there are uncontrollable situations in which files get deleted.
A good deleted files recovery software is the best and the only solution for recovery of deleted files.
