  1. 1. How to Recover Deleted Files withFree Software Adam Pash —Ack! The computer ate my term paper! Weve all been there at some point. You delete animportant file, somehow it skips your Recycle Bin altogether, and for all practical purposes, itsdisappeared into the ether. But before you hit the big red panic button, theres a very good chancethat your file is still alive and kicking somewhere on your hard drive—you just need to know howto find it. With the right tools, finding and recovering that deleted file can be as simple as a fewclicks of your mouse.Part I: The OverviewOk, so youve lost an important file. Dont panic. Take a breath, and lets see if we can find it.Before you go into full-on file recovery mode, make sure you double-check the folder you hadsaved it in and the Recycle Bin or Trash. Still nothing?1. Stop What Youre DoingWhen your operating system deletes a file, all it really does is mark the space on your hard drivethat your file occupies as free space.

Find the Right File Recovery ProgramWindows: Youve a lot of really great freeware options for file recovery if youre runningWindows. Notable apps include Undelete Plus (original post), PC Inspector File Recovery(original post), and Restoration (original post). Undelete Plus is the most user-friendly option ofthe bunch, with advanced filtering options that make it easy to find your needle of a file amongthe haystack of deleted garbage, but in my tests I found both Restoration and PC Inspector FileRecovery to be more effective at recovering files. (Of course, your mileage may vary.) As an addedbonus, the bare bones Restoration is portable, which makes it an excellent addition to your thumbdrive.UPDATE: Per several readers advice, you may also want to check out Recuva (original post),another freeware Windows file recovery tool.Mac: If youre on a Mac and arent afraid to lay down a few bucks in the name of data recovery,the $99 Data Rescue II is the go-to application for file recovery with a friendly graphical interface.

Recover Your Files
  3. 3. Once youve picked a tool, its time to scan your harddrive for your lost file or files. This process variesdepending on the app youre using, but its basically thesame for all of them: Just point the program at thehard drive or folder that was holding your missing fileand start your scan. Once the scan is complete, youregoing to see a big list of jumbled file names. Often mostof these files are nothing more than system files thatyour operating system has created in the course ofbasic operation, and you wont need to worry aboutthem.
