HISTORY FFS was introduced with version 1.3 of AmigaOS in 1988. With version 3.0 of AmigaOS, born for the new amiga 4000 were introduced new FFS modes, called International and Directory Cache. International mode allows FFS to handle filenames with international characters. Directory Cache mode allows the filesystem to access hard disks more rapidly by creating a cache of directory contents. As any other directory caching based systems it used a certain amount of disk space to store the data. Relatively recently MorphOS and the presently unreleased AmigaOS4 have introduced support for new FFS2 filesystem Or '''Fast File System 2'''. Normal (or "ancient") FastFileSystem is outdated compared to more modern file systems; it lacks the reliability and advanced features of more modern offerings. FFS stores a "map" of the filesystem in a bitmap which is prone to deletion or corruption if the OS is reset or crashes during a write, resulting in data loss or invalidation of the filesystem. FFS2 is a minor update of FastFileSystem for AmigaOS4 and MorphOS; it implements long filename support whilst maintaining backward compatibility with the older FastFileSystem and OldFileSystem. However its only major addition is the capability of handling longer filenames, and still suffers from the negative points of FFS, but is still maintained for legacy purposes. CHARACTERISTICS The Amiga Old File System article, in the section "Characteristics" , presents the basic information regarding Amiga filesystems specifications. SEE ALSO EXTERNAL LINKS
