Larger hypertext systems
========================
During this last year, I have built several commercial hypertext
systems, with many thousands of files and 120,000 plus cross-links.
To make the hypertext jumps instantaneous, I keep each file small,
and limit each directory to 128 files. How does this work?
Files With any hypertext jump, Hyplus first searches the directory
===== containing the Hyplus program. If the file is not found in this
directory, the Hyplus program then searches the subdirectory named
by the first three characters of the file name.
Speed Using this automatic subdirectory method, I've seen no reduction in
===== hypertext performance with several hundred subdirectories.
However, because PC-DOS allocates 4K per file regardless, a 32 Meg
hard disk is effectively limited to 8,000 files regardless of the
size of each file. The solution?
I put my larger systems on CD-ROMs <link15 1 14>, which lets
Hyplus rapidly access over 240,000 pages of text using our unique
rapid file-access system -- change to subdirectory then read file.
