Advanced Disc Filing System
The Advanced Disc Filing System ( ADFS ) is a file system that was developed by Acorn for their RISC OS operating system . In contrast to the older Disc File System ( DFS ) of the RISC-OS predecessor Arthur , it no longer has any problems with fragmentation .
It supports file names with a length of 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 expanded to include 800k double-density and 1600k high-density floppy disks .
In the current version of ADFS, there is virtually no limit to the characters in the file name and the number of files per directory.
This file system can be easily mounted under Linux .
