Article: How to unerase files?

Introduction.

If an important file gets erased by mistake, it can be quite frustrating. Hours, weeks, or even months of hard work can simply disappear, leaving you with nothing but a portion of free space on your hard disk, memory stick, or whatever storage device you used. A thought of repeating the same work once again seems exasperating, you are ready to throw your monitor out of the window (this unfortunate device tends to attract the very first hit, even though it doesn't really participate in processes inside the computer).

Don't do that. It's not very expensive nowadays, but you may hurt somebody. Besides, there are better solutions to the problem.

Files erased by mistake or by a virus can be restored with a program like DiskInternals Uneraser. The latter program has rich preview capabilities (deleted files can be previewed before taking any actions) and can restore even those files that cannot be found by simple undelete programs (it scans the entire surface of the disk or the entire storage area).

Step 1: Download and install the program.

First of all, don't use the device where you need to restore erased files. Download and install the program to another volume.

Download DiskInternals Uneraser to a known location. Run the downloaded package and follow on-screen instructions to install it.

Step 2: Launch the program. Select a storage device and file type.

Start DiskInternals Uneraser. The program will automatically detect all storage devices that are connected to your system. Then the wizard starts:

File recovery wizard

Click "Next". This takes us to the following page (the list of storage devices will be different on your system):

Select device to unerase files

Select the device you want to unerase files on. You can also specify folders for the program to look in. When ready, click "Next".

Step 3: Scan for erased files.

The wizard will ask you what file types and filenames you are looking for. If you are not sure about file types or about filenames, you can simply use the default option. This will let the program list all erased files on the given storage device.

Enter filenames and file types to unerase

Click "Next" to continue. The wizard will show a summary page:

Unerase summary

Click "Next" to start scanning. Depending on size and performance characteristics of your storage device, the scanning process may take some time. With smaller devices, it may be almost instant:

Erased files found

When the program has finished scanning, click "Finish" to exit the wizard and preview found files.

Step 4: Preview and restore erased files.

DiskInternals Uneraser creates virtual folders for erased files. In these folders erased files are sorted by their type (text documents, MP3 files, videos etc.), so that it is easy to find necessary files. Virtual folders can be found in the "Recovered files" folder.

Recovered files

Some files may have already lost their filenames. DiskInternals Uneraser gives such files new filenames, like "file_0000", "file_0001" etc. If you don't find your file among the ones with proper filenames, you may take a look at these files. Use the preview feature to see (or hear) the contents of such files.

The preview feature is important not only for detecting the right file. If you use the trial version of DiskInternals Uneraser, you cannot recover files before registering. By previewing erased files you can decide if you need to register your copy. A complete preview means that the file is not partially overwritten or otherwise damaged and can be restored completely, with a 100% guarantee.

Once you have found erased files that need to be restored, select the files and click "Recover" on the program's toolbar. Alternatively you can right-click the files and select "Recover" from the context menu.

A simple recovery wizard will be started. Choose recovery method:

Save erased files

and path:

Choose a folder for restoring erased files

Then click "Next" to unerase files.

It is recommended to save files to another drive, not the same one you are recovering them from.
