Amiga Fast File System
open-in-new
<p>The Amiga Fast File System (abbreviated AFFS, or more commonly historically as FFS) is a <a href="/facts/File_system/FdPm90uc">file system</a> used on the <a href="/facts/Amiga/60B3A9of">Amiga</a> <a href="/facts/Personal_computer/koaYfNce">personal computer</a> from the computer-manufacturer <a href="/facts/Commodore_International/SlfXKbCN">Commodore Int'l.</a>. The previous Amiga filesystem was never given a specific name and known originally simply as "DOS" or <i>AmigaDOS</i>. Upon the release of FFS and for purposes of differentiation, the original filesystem became retrospectively known as <a href="/facts/Amiga_Old_File_System/qEso6gy3">Amiga's <i>Old File System</i></a>, shortened OFS. The former file-system OFS, which was primarily designed for use with floppy disks, had been proving slow to keep up with hard drives of the era. </p><p>FFS was designed as a full replacement for the original Amiga filesystem. FFS differs from its predecessor mainly in the removal of redundant information. <a href="/facts/Data_block/S3vT7c6N">Data blocks</a> contain nothing but data, allowing the filesystem to manage the transfer of large chunks of data directly from the <a href="/facts/Host_adapter/nQbbDHF2">host adapter</a> to the final destination. </p>
