VxWorks support these filesystems: FAT, NFS, raw, TrueFFS, SCSI support

There is also another file system - The Target Server File System (TSFS). FSFS is a full-featured VxWorks file system, but the files operated on by using the file system are actually located on the host. TSFS uses a WDB driver to transfer requests from the I/O system to the target server. The target server reads the request and executes it using the host file system. Thus when you open a file with TSFS, the file being opened is actually on the host. Future read() and write() calls on the file descriptor obtained from the open() call actually read from and write to the opened host file.
