About the DiskTracker Manual
The DiskTracker Manual was created using eDoc version 1.1.1. It is a self-reading document, so to read it, just double click the "DiskTracker user manual" icon.
In addition, a copy of the manual, saved in the Microsoft Word 4.0/5.x format (should be readable by just about any known Mac word processor), is available for downloading from the DiskTracker web page (http://web.mit.edu/mnp/www/dt.html).
Memory allocation issues
DiskTracker's default memory allocation is set to 1000K. On PowerMacintoshes, this goes up to nearly 1500K if Virtual Memory is turned off or Connectix RAMDoubler is not installed. This default allocation should be sufficient for most users of DiskTracker, because of its built in virtual memory system. In fact, DiskTracker should run acceptably with the minimum memory allocation of 600K. For instance, I have often worked with a 16MB catalog file using only 512K of RAM (this catalog file contained catalogs of over 60 CD-ROMs, totalling nearly 300,000 files). Naturally, increasing the memory partition will cause an increase in speed when dealing with large catalog files.
Because DiskTracker uses your hard drive space to store large catalog files, you should be sure that you have around one and a half times more disk space availble on your disk than the size of the saved catalog file (this 1.5x figure comes from the fact that the data in DiskTracker files is stored differently than the data in DiskTracker's active memory (the data on disk is optimized for size, while the data in memory is optimized for speed)). So, if you run into trouble running DiskTracker, make sure that there is sufficient space available on your hard drive.
Shareware issues
DiskTracker is a shareware program ($20). Registration is handled by Kagi Shareware. For more information, see the Registration Read Me in the DiskTracker Registration folder. Please register DiskTracker if you use it - I spent a good amount of time and effort working on this project.
That's all for now! For any additions and updates to the information in this Read Me, check out the DiskTracker web page.
