Data recovery is one of the major problems every PC user has faced at least once in his/her life. Sometimes, we delete files in error or perhaps format hard drives, however recall that some important files have been deleted. It's not an issue if this sounds like only a folder with documents you have in your email box or movies that you will surely download later. The problem gets bigger if these docs contain important commercial information or else you lost security keys to access your financial accounts. Regardless, loss of data is "no joy" at all.
