Recuva is free file recovery software that allows you to recover photos and documents accidentally deleted from your hard drive–even if you have removed them from your Recycle Bin.
This free software from Piriform even recovers deleted files from USB sticks. One of the most impressive features of this software is it can even recover lost emails, and another great advantage of Recuva is a portable version that allows you to install a version on a CD or USB drive and take it with you.This software is a must have for techs in the field as well as normal computer users. Recuva can perform a deep scan in a few minutes and recover files that were delete long ago. As with any file recovery program, the more you use the hard drive after deleting a file, the less likely you will be able to recover it.
Recuva can also permanently shred files you never want recovered. This is great is you plan on selling the PC and do not want to risk having private documents recovered by strangers or snoops.
But the best technique for recovering files is to never lose them at all. Be sure to have a redundant method of backing up at home. A Network Attached Storage device (NAS) is a convenient way to share a large drive with other computer in the house. At the very least, backup weekly to another hard drive or an online service like Carbonite.
