It was used in the Novell NetWare operating system. It is the default and only file system for all volumes in versions 2.x through 4.x, and the default and only file system for the SYS volume continuing through version 5.x. Novell developed two varieties of NWFS:
Novell Storage Services (NSS, released in 1998), superseded the NWFS format. The NWFS on-disk format was never publicly documented by Novell. The published specifications{{Citation needed|date=December 2010}} for 32-bit NWFS are:
For larger files the file system utilized a performance feature named Turbo FAT.{{citation needed|date=May 2014}} Transparent file compression was also supported, although this had a significant impact on the performance of file serving. Every name space requires its own separate directory entry for each file. While the maximum number of directory entries is 16,000,000, two resident name spaces would reduce the usable maximum number of directory entries to 8,000,000, and three to 5,333,333. 16-bit NWFS could handle volumes of up to 256 MiB. However, its only name-space support was a dedicated API to handle Macintosh clients. See also
