How to: Recover deleted files

Accidentally erased important documents? Here's how to get them back.

If you've accidentally deleted a file from your computer, you're likely to be panicking you'll never see it ever again. But worry not! If you've deleted something from a Windows-powered computer, the likelihood is it isn't lost forever and you will be able to recover it again.

There are also lots of methods you can use to get that file back, so if one doesn't work, you can always try an alternative.

But if the file isn't recoverable, you've learnt a very important lesson: always back up your computer or save files to cloud storage like Dropbox, which allows you to reinstate files you've either accidentally deleted, or removed because you didn't think you needed them anymore (although you can only restore files for a limited time period in most cases).

It's a very good idea indeed to get into the habit of following best practice to avoid the panic of unrecoverable files in the first place. These top three tips will help you keep your files as safe as possible and if something is deleted accidentally, you'll be able to restore to a back if you need to.

The first (pretty obvious) step to take is to always back up your data. Schedule daily backups so you won't lose too much if your hard drive is inadvertently wiped.

If you think your PC has picked up a virus, stop using it straight away. The less you use your computer, the more likely it is you'll be able to restore those files.

If you're not already using the cloud to back up your data, consider making the jump. This means even if your computer dies, you'll still have backups to restore to in the cloud, completely independent of your computer or internal network.

Recycle Bin

First things first: check the Recycle Bin. Odds are, you've seen it in the top left corner of the desktop, but you may not have used it before.

For those that aren't familiar, this is where Windows stores files and folders once you hit delete. It exists for precisely this reason - to act as a fall-back option when users accidentally delete something they didn't mean to.

Be warned, though; this method isn't infallible. For starters, it will only save files deleted from the hard drive, whereas anything deleted from network storage or removable media is instantly wiped.

There's also a limit to the Recycle Bin's capacity. Once it hits a certain size, older files will be permanently erased to make way for newly deleted ones. To modify this limit, right click on the Recycle Bin icon and select properties.

To recover files from the Recycle Bin, click the icon on the desktop. From there, you can choose to select specific files to restore or restore everything in the Recycle Bin.

Disk recovery tools

If the files you're after aren't in the Recycle Bin, there's still hope in the form of third-party data recovery tools. When files are deleted by the user, the data isn't removed from the hard drive right away - Windows simply marks in the Master File Table that it's OK for the system to overwrite it.

In practice, this means that if you refrain from using your computer (like we advised at the start of this article), there's a good chance that the data is still lurking somewhere on the disk.

There are many tools available to recover deleted files, but one of the most popular is Piriform's Recuva utility. It's simple to use, and best of all, the portable version of the software requires no installation.

Once you've downloaded Recuva Portable, simply unzip the file to a USB drive. You can then plug it into any computer, and use Recuva to scan for deleted files on that machine's hard drive.

 

Click on the Recuva.exe icon (or Recuva64.exe for 64-bit operating systems) to launch the utility. From there, you can specify which type of file you're looking for, as well as where it might be located.

The software will then scan for recoverable files. Once it's finished, select the files you want to restore and click 'recover'. You can choose which drive to restore the files to, and it's advisable that you restore them to a different drive than their original location.

Restore from a backup

We've mentioned it once already, but it bears repeating: restoring from a backup is the best way to recover lost files. There's absolutely no reason not to regularly back up your system, whether you're an SMB or an average user.

There are numerous different ways to back up your files, from cloud-based systems to physical appliances, but one feature they all share is that restoring from a backup is fairly quick and easy.

Professional assistance

As a last resort, you can turn to professional data recovery services that will attempt to extract your files from an otherwise inoperable drive. Have a look online to find your nearest one, but be sure to check out some of their reviews first.

However, these firms should be used only when all else has failed, as their fees can be steep, and success is decidedly not guaranteed. In fact, this option should generally only be considered if the lost data is extremely valuable or genuinely irreplaceable.
