The tool includes a snapshot feature that allows users to save the current state of conversion and resume it later, eliminating the need to restart the process. These capabilities make the software particularly valuable for IT administrators managing large user databases, data migration experts, and businesses of all sizes requiring reliable OST file recovery and conversion.
