[edit] Overview
The Disc Filing System (DFS) was the filesystem format used for floppy disks by Acorn's early 8-bit computers, such as the BBC Micro. Acorn single density 5¼" disks would typically contain a DFS filesystem.
DFS was a very simple filesystem, supporting a only small number of contiguous files with 7-character names in a flat structure (although files could be assigned to single-letter "directories", similar to CP/M's user numbers).
DFS was superseded by the Advanced Disc Filing System (ADFS), which was available on Acorn's later 8-bit computers such as the Master Compact (and more commonly used than DFS on that machine's 3½" disks), as well as the 32-bit Archimedes and later.
