.AFM File Extension

ASCII text-based font format developed by Adobe; stores font metric data for a Type 1 PostScript file; contains the master design of a specific font, which defines the way each character of the font looks.

Metadata file created in the Advanced Forensics Format (AFF), a file format used to save disk image data for digital evidence; saves only the metadata that was extracted out of an .AFF disk image file; allows the metadata to be separated from the raw disk image data.

AFM files reference the AFF disk image data. When opened, the supporting program automatically locates the disk image data in the separate files and loads it appropriately.
