NetWare Filesystem (NWFS) is a FAT-like filesystem made by Novell for their NetWare filesystem. There are two kinds of NWFS, 16-bit and 32-bit. 32-bit NWFS is equivalent to FAT32. NWFS could support a maximum filesize of 4.2GB and could be on a maximum volume of a little over one terabyte. NWFS supported a special type of journaling called Novell Transaction Tracking System (TTS) and transparent file compression. NWFS also supported file salvaging (undeleting files). The file-naming supported double-byte ASCII. In 1998, NWFS was made obsolete by the Novell Storage Services (NSS) Filesystem.
