NAME

       udfs - universal disk format file system

DESCRIPTION

       The  udfs  file	system is a file system type that allows user access to files on Universal Disk Format (UDF) disks from within the Solaris
       operating environment. Once mounted,  a udfs file system provides standard Solaris file system operations and semantics. That is, users can
       read  files, write files,  and list files in a directory on a UDF device and applications can use standard UNIX system calls on these files
       and directories.

       Because udfs is a platform-independent file system, the same media can be written to and read from by any operating system or vendor.

   Mounting File Systems
       udfs file systems are mounted using:

       mount-F udfs -o rw/ro device-special

       Use:

       mount /udfs
	if the /udfs and device special file /dev/dsk/c0t6d0s0 are valid and the following line (or similar  line)  appears  in  your  /etc/vfstab
       file:

       /dev/dsk/c0t6d0s0 - /udfs udfs - no ro

       The udfs file system provides read-only support for ROM,  RAM,  and sequentially-recordable media and  read-write  support
	on RAM media.

       The  udfs file system also supports regular files, directories, and symbolic links, as well as device nodes such as block, character, FIFO,
       and Socket.

SEE ALSO

       mount(1M), mount_udfs(1M), vfstab(4)

NOTES

       Invalid characters such as "NULL" and "/" and invalid file names such as "." and ".." will be translated according to the following rule:

       Replace the invalid character with an "_," then append the file name with # followed by a 4 digit hex representation of the 16-bit  CRC	of
       the original FileIdentifier. For example, the file name ".." will become "__#4C05"
