In most cases yes. Generally those situation are limited to a user accidentally emptying the recycle bin containing important files. In this case recovery programs can help with a “simple file deletion” problem. However when the hard drive, USB flash drive, memory card, internal or external hard drive has been reformatted, lost partition or partially overwritten then file recovery will require some more sophisticated professional data recovery tools generally requiring a fee to perform a deep scan. Before performing any scanning for deleted data with any software make sure to create an image of the drive and never install any software or recover data to the same source drive as that can overwrite the deleted data. If the data absolutely cannot be lost contact a professional data recovery company for assistance.
