O&O FormatRecovery V4, guided by an on-screen Assistant, enables the recovery of deleted or formatted partitions or hard disks to their pre-deletion form. File and directory information is likewise restored. By use of a specially developed algorithm, O&O FormatRecovery V4 can search for files through formatted or deleted disks and restore them even when the data are heavily fragmented! In contrast to O&O UnErase V4 and O&O DiskRecovery V4, O&O FormatRecovery V4 can also restore files with missing directories and configuration information.
