If you’ve deleted a partition (or reformatted a drive), traditional file recovery fails because the partition table is missing. EF v7.7 scans the entire drive’s surface, finds partition boundaries based on boot sectors and file system metadata, and allows you to extract files from "lost" or "orphaned" partitions.
