Generally, yes. Recuva is a file recovery program that can recover data that has been permanently deleted from your computer. Data that has been accidentally deleted or lost will not be recovered with this software, but you may be able to restore it using other means if the files are still present on your system.   Recuva works by scanning through all of the partitions on your hard drive and recovering any files that were hidden (to protect them) or encrypted with FileVault 2 encryption. Depending on how much information was lost, Recuva may take some time to complete its scan.
