If the file is not backed up, it is deleted, and the garbage collector is emptied, how do we restore the data?
First, think back to the possibility that these files could exist somewhere else, such as a removable hard disk, a mailbox, a variety of cyberspace, or a memory card, etc. If not, you must immediately close some of the software you are using, especially if you want to stop using all the real-time catalog indexing software such as X1, Google Desktop, or the Windows system's own Indexing Service, they all have the potential to completely erase the files you want to recover.
Then, use the Quetek file scavenger or Diskeeper undelete program to help you find the files you want to recover from your hard disk. Also, if the file recovery program cannot find the deleted file, then you can consider some of Vista's new features for recovering deleted files The shadow copy feature restores files by right-clicking the folder that was stored before the deleted file, and selecting the "Revert to last" option, It is generally possible to retrieve the deleted files.
