Explanation

File carving is a digital forensics technique that recovers files directly from raw disk data without relying on filesystem metadata (which may be corrupted or deleted). Recovery depends on recognizing file format signatures-known byte patterns called 'magic numbers' that appear at the start of a file's header. For example, JPEG files begin with FF D8 FF and PNG files begin with 89 50 4E 47. By scanning raw disk sectors for these header patterns (and optionally footer patterns), forensic tools can identify and extract complete image files even when directory entries are gone.
