File Extension ADF

File type: Amiga Disk File

About the ADF file type:

If Windows cannot find the appropriate program associated with .ADF files, then your registry may have errors. Check your Windows registry for errors (includes file association errors).

The ADF file extension identifies the disk image generated on the Amiga computer system used for storing an exact duplicate of the Amiga formatted disk using fixed width AmigaDOS data tracks. This format can be mounted like a typical physical disk by using an emulation program that supports the Amiga system. It is possible to create the ADF format files under a Microsoft Windows Operating System environment by utilizing the ADF Opus application. The ADF file extension represents the standard format utilized by both the Amiga computer and emulator applications for creating disk images which has been in use almost since the computer system was introduced into the IT market. Prior to being adapted as the ADF format, it was widely deployed for the production of commercial computer games, disk virtualization, and creation of backup files. Technically, the ADF file extension isn't a file format; it is more of a 'track by track' dump representing disk data as it was interpreted by the Amiga OS.

Majority of the ADF file extension images of the Amiga formatted tracks are stored in the cylinders zero to 79 when dealing with standard double density 3.5-inch floppy disk media or more commonly known as 880Kb disk in Amiga communities. The associated file size for an ADF file format would usually vary based on the number of tracks incorporated into the image. In practice however, the ADF files normally have a size of 901120 bytes based on the 80 cylinders, two heads, 11 sectors, and 512 bytes per sector. Most of the applications running on the Amiga platform were distributed in the market using Double Density floppy media which at the time were more popular than the high density 3.5-inch floppy disk capable of storing a maximum of 1.76Mb data. The 5.25-inch double density discs were also supported by the Amiga computer system. EasyADF is an application which supports the creation of an ADF file type in Amiga disks while the ADF Opus allows the conversion of ADF file extension to ADZ format files.
