'''Netware File System''' ('''NWFS'''), is a [[file system]], based on a heavily-modified version of [[File Allocation Table|FAT]],. It was used byin [[Novell, Inc.|Novell]]'s [[Novell NetWare|NetWare]] Operating[[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. There were two varieties of NWFS: 16-bit NWFS 286, used in Netware 2.x; and 32-bit NWFS 386, used in Netware 3.x through Netware 6.x. It was superseded by the release of [[Novell Storage Services|NSS]] in 1998.

The published specifications for NWFS are:

Line 16:

* Support for different name spaces: [[Microsoft]] [[Microsoft Windows|Windows]] Long names, [[Unix]], [[Apple Computer|Apple]] [[Apple Macintosh|Macintosh]]

Transparent file compression was also supported, although this had a significant impact on the performance of file serving.

Note: Every name space which is loaded takes up the same amount of directory entries, so while the maximum directory entries is 16,000,000, that is only with 1 name space loaded. Two name spaces reduce the usable directory entries to 8,000,000 (8,000,000 per name space). Three name spaces loaded reduce the maximum directory entries to 5,333,333 (5,333,333 per name space).

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.
