HISTORY FFS was introduced with version 1.3 of . Copy of BIX announcement from USENET . AmigaOS 3.0, designed for the Amiga 4000, introduced two new FFS modes:
As any other directory caching based systems it used a certain amount of disk space to store the data. More recently, MorphOS and AmigaOS 4 have introduced support for a slightly updated Fast File System 2, or '''FFS2'''. Like the normal (or "ancient") FastFileSystem, FFS2 is outdated compared to more modern file systems. It lacks the reliability and advanced features of more modern offerings. All FFS versions store 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 AmigaOS 4 and MorphOS. It implements long filename support while 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. It is still supported only for legacy purposes. CHARACTERISTICS The Amiga Old File System article, in the section "Characteristics" , presents the basic information regarding Amiga filesystems specifications. REFERENCES SEE ALSO EXTERNAL LINKS
