Despite the inclusion of the word “pro” in the name, this program is still free; there is, in fact, no non-pro version.
The look of UnDeleteMyFiles Pro may not be particularly appealing, but don’t let that put you off too much as there are multiple tools included here, not just data recovery. Recovery can be a little hit and miss as there is no indication of the quality (or recoverability) of files – you just have to hope that the file that are found are in a reasonable state.
When it comes to data recovery, there aren’t really all that many options other than the ability to search for particular types of files to reduce the size of the list you have to sort through.
In terms of extras you also get a disk snapshot tool which basically backs up your drive so you can recover data at your leisure, a secure file deletion tool, and email recovery. Worth checking out, even if this is not necessarily the best of the bunch.
