FILE SYSTEM TYPES

Solaris uses VFS (Virtual File System) Architecture. This provides standard interface for different FS types. It is called VIRTUAL because the user can issue same command to work regardless of the file system.

SUPPORTED FS TYPES BY VFS:

1.  DISK BASED FS

2.  DISTRIBUTED FS

3.  PSEUDO FS
