z/OS File System (zFS)

z/OS File System (zFS) is a z/OS UNIX file system. zFS file systems contain files and directories that can be accessed with z/OS UNIX application programming interfaces (APIs). These file systems can support access control lists (ACLs). zFS file systems can be mounted into the z/OS UNIX hierarchy along with other local or remote file system types (for example, TFS, AUTOMNT, and NFS).
