- Larger hypertext systems <sum03 1 10>
- ========================
-
- During this last year, I have built several commercial hypertext
- systems, with many thousands of files and 50,000 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, HyperRez first searches the directory
- ===== containing the HyperRez program. If the file is not found in this
- directory, the HyperRez 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
- HyperRez rapidly access over 240,000 pages of text using a unique
- rapid file-access system (one CD head read) in PC-Hypertext.
