UnixWare is a hierarchical file system; as with NetWare the top of the tree is called the root node and labeled as ``/''. A file system is mounted at a particular UnixWare directory at or below root and appears as directories to the users.
NetWare uses a modified hierarchical file system, with multiple root nodes called volumes. Each volume has its own tree structure, and users must switch volumes to access the volume's resources. ``NetWare volumes compared with the UnixWare file system'' illustrates the topological differences between the NetWare and UnixWare file systems.
For security reasons, files that control operation of the UnixWare system should not be included in a NetWare volume.

NetWare volumes compared with the UnixWare file system
Because UnixWare has no concept of a ``volume'', NetWare volumes become paths to a particular point in the UnixWare file system. In ``NetWare volumes compared with the UnixWare file system'', root directories /sys, /home, and /work become NetWare volumes by specifying the path in the NetWare Services voltab file using the scoadmin(1M) NetWare Volume Setup utility.
NetWare supports a maximum of 64 volumes, and NetWare Services allows the 64 volumes.
