How to Recover Deleted Files with Free Software

Ack! The computer ate my term paper! We've all been there at some point. You delete an important file, somehow it skips your Recycle Bin altogether, and for all practical purposes, it's disappeared into the ether. But before you hit the big red panic button, there's a very good chance that your file is still alive and kicking somewhere on your hard drive—you just need to know how to find it. With the right tools, finding and recovering that deleted file can be as simple as a few clicks of your mouse.

Part I: The Overview

Ok, so you've lost an important file. Don't panic. Take a breath, and let's see if we can find it. Before you go into full-on file recovery mode, make sure you double-check the folder you had saved it in and the Recycle Bin or Trash. Still nothing?

1. Stop What You're Doing

When your operating system deletes a file, all it really does is mark the space on your hard drive that your file occupies as free space. It's still there, but your computer is now perfectly happy to write new data on top of it—at which point the file recovery process becomes a lot more difficult. That means you should do as little computing as possible until you find the file you're looking for, since every time you save a new file—every time your computer writes information to your hard drive—your chances of recovering the file go down.

2. Find the Right File Recovery Program

Windows: You've a lot of really great freeware options for file recovery if you're running Windows. Notable apps include Undelete Plus, PC Inspector File Recovery (original post), and Restoration (original post). Undelete Plus is the most user-friendly option of the bunch, with advanced filtering options that make it easy to find your needle of a file among the haystack of deleted garbage, but in my tests I found both Restoration and PC Inspector File Recovery to be more effective at recovering files. (Of course, your mileage may vary.) As an added bonus, the bare bones Restoration is portable, which makes it an excellent addition to your thumb drive.

UPDATE: Per several readers advice, you may also want to check out Recuva, another freeware Windows file recovery tool.

Mac: If you're on a Mac and aren't afraid to lay down a few bucks in the name of data recovery, the US$99 Data Rescue II is the go-to application for file recovery with a friendly graphical interface.

3. Recover Your Files

This process varies depending on the app you're using, but it's basically the same for all of them: Just point the program at the hard drive or folder that was holding your missing file and start your scan. Once the scan is complete, you're going to see a big list of jumbled file names. Often most of these files are nothing more than system files that your operating system has created in the course of basic operation, and you won't need to worry about them. You're just looking for the file type and name that matches what you've lost.

Once you find what you're looking for, saving it is a matter of right-clicking the file and choosing where to save it.

Went through steps one through three and still aren't having any luck? It might be worth trying again with a different application, since there can be a lot of variation between apps. If you're still not having any luck, part two discusses a few other ways you can try addressing more specific problems when your data goes missing.

Part 2: More Specific Problems

Above you got a basic overview for recovering deleted files from your computer. Now we'll take a closer look at some more specific problems, methods of data recovery, and tools that may be of help in your quest for your elusive lost data.

Recover Files from a Wiped or Unbootable Hard Drive

hard-drive-pic.pngSo you didn't just accidentally delete a file or two and empty your Recycle Bin prematurely—instead you've got a whole hard drive worth of missing data. You can still use many of the applications mentioned above to recover files from these drives as long as you have or can get the hard drive into a bootable computer. For more details, check out how to recover files from a wiped hard drive with PhotoRec (original post) or how to recover data from a crashed hard drive with PC Inspector File Recovery (original post).

If you can't or don't know how to get your unbootable drive into another computer, a Linux live CD can be perfect for rescuing files. If the Linux route scares you off, give the popular BartPE (original post) a try.

Finally, if none of these options can even read your hard drive, you still might be able to get it working for just long enough with a few tricks of the data recovery trade, like putting the busted hard drive in the freezer.

Recover Lost Photos

That said, you can find other applications, like Zero Assumption Digital Image Recovery (original post), that are focused specifically on image recovery that you may want to add to your data recovery toolbox.

Recover Lost Word Documents

If your lost dissertation was saved as a Word document, you've got a few more interesting options for getting to your lost or deleted documents—read more about them here and here.

Recover Data from Scratched or Corrupted CDs and DVDs

Freeware application CD Recovery Toolbox is made specifically to read the portions of a CD that are readable in an effort to rescue as much data as possible from a damaged disc. If that doesn't work, you may want to give a look at the 30-day trial of shareware application CDCheck. Then again, if scratches are the issue, you may be able to get away with simply fixing your scratched CD or DVD yourself.

Part 3: Don't Let This Happen Again

backup.pngWhatever the cause of your lost file, the best method of data recovery is a good preemptive data backup plan. If you're on Windows, we've taken you step-by-step through how to automatically back up your hard drive so that this sort of thing never happens again. If you're running a Mac, do yourself a favor: Get an external hard drive and flip the switch on the easy-to-use Time Machine. Linux users should check out backup options like FlyBack, TimeVault, or the time-honored rsync.

    If you had used an online backup tool such as Carbonite you wouldn't have that problem. Just click restore and you have it all back. That is why it is the simplest system to use.

    I have lost all my music and tried systems restore with no luck Any suggestions please

    I've used a linux boot cd to recover a friends itunes collection deleted and emptied from the trash. Also used a it to recover a failed HDD (linux server) using dd_rescue plus the ext2 debugfs tools. Finally, this week I used dd_rescue again to recover a failed windows HDD and managed to restore ALL the data (drive was having write errors but read was ok).

    Just wanted to let you know that Disk Drill, new data recovery software for Mac, was recently released:) Check it here:

    To recover the deleted, files and folders it is recommended using effective mac data recovery software that applies strong & sophisticated programming algorithms to extract and locate the files for restoration. I used it to recover files from my system after the drive was formatted, it works really efficiently.
