.AFM File Extension

An AFM file may also be a metadata file saved in the Advanced Forensics Format (AFF) that is used in digital forensics to store information extracted from an .AFF disk image file. It allows users to analyze and preserve metadata separately from raw disk image content.

AFM files facilitate the forensic process by enabling software to reference metadata independently, thereby maintaining data integrity and allowing more efficient access and analysis. The AFF format, including its metadata component AFM files, is widely utilized in forensic investigations to ensure thorough documentation and support chain-of-custody procedures.

Typically, investigators generate AFM files when they create or analyze an AFF disk image. The format remains current and is still used in forensic science due to its comprehensive approach to managing both disk images and associated metadata.

You can open AFM files with PassMark OSForensics and Smart Projects IsoBuster. AFFLIB also supports AFM files, but it is discontinued.
