What is an AFF file?

Advanced Forensic Format image
Advanced Forensic Format is a file format used for exact disk images with or without compression. It also stores the related metadata within the disk images or separately.
AFF files divide into two layers. One is the disk-representation layer, and the other is the data storage layer. The disk-representation layer specifies segment names and represents the information on the disk image. The data storage layer uses XML or binary to store segments.
The disk image contains an exact copy of a suspect's device, which forensic experts can analyze.
