Even though data recovery software and undelete utilities are both designed to recover deleted and lost files, they are different in two ways: data recovery software offers you multiple functions to handle many different situations, and it can also recover a lot more data. Cost reflects quality. The best way to figure out the level of software is by the price. Anything you find priced under $75 USD means it’s an undelete program; they usually fall within the price range of $35 to $40, but some are higher.
