What is an ADF file?

ADF is an acronym for Amiga Disk File. Files that contain the .adf file extension store disk image files that have been created on an Amiga system.

The ADF files that are created by a user store an exact copy of the user's Amiga-formatted disk and can be mounted as a physical disk on a user's operating system by using an Amiga emulation software application.

The ACT! Customer relationship management software also uses the .adf file suffix. These ADF files contain database files that have been created with the ACT! application. Each ADF file is saved with an associated ALF file that is used to navigate the data contained within the database.
