Have you ever accidentally deleted a file? Or simply need a file you’ve already emptied from your Recycle Bin? FreeUndelete (name says it all), is available at no charge for non-commercial use at http://www.officerecovery.com/freeundelete/
Granted, this isn’t the most user friendly tool, but I want to make sure you know there are options available.
Tips for use: files may not retain their original filename. Sort by date for reference. If you ever know you have lost something, immediately stop using your computer and shut it down until ready for recovery. The longer data is being written to the drive, the less chance of recovery.
