Excerpt
.1. Long File Names File names can now be of nearly arbitrary length. Only programs that read directories are affected by this change. To promote portability to UNIX systems that are not running the new file system, a set of directory access routines have been introduced to provide a consistent interface to directories on both old and new systems. 5.3. Symbolic Links The traditional UNIX file system allows multiple directory entries in the same file system to reference a single file. Each directory entry "links" a file's name to an inode and its contents.

Claims
Long file name associated with short file name

In a computer system having a processor running an operating system and a memory means storing the operating system, a method comprising the computer-implemented steps of: (a) storing in the memory means a first directory entry for a file wherein the first directory entry holds a short filename for the file, said short filename including at most a maximum number of characters that is permissible by the operating system; (b) storing in the memory means a second directory entry for a the file wherein the second directory entry holds a long filename for the file and wherein the second directory entry includes an attributes field which may be set to make the second directory entry invisible to the operating system and the step of storing the second directory entry further comprises the step of setting the attributes field so that the second directory entry is invisible to the operating system, said long filename including more than the maximum number of characters that is permissible by the operating system; and (c) accessing the first directory entry with the operating system.
