Advanced Disc Filing System

The Advanced Disc Filing System (ADFS ) is a file system that has been developed by Acorn for their operating system RISC OS. In contrast to the older Disc File System (DFS) of the RISC OS predecessor, Arthur has no more problems with fragmentation.

It supports file names up to 10 characters and a maximum of 77 files in a directory. It was initially limited to 3.5'' floppy disks with a capacity of 640k, but was later extended to include 800k - 1600k double-density and high-density diskettes.

In the current version of ADFS there is virtually no limit to the characters in the file name and number of files per directory more.

Under Linux can easily mount this file system.
