Your response to my statement of which interfaces CD-ROM applications support and why is highly overrated. 1) I agree that many apps do not require MSCDEX. However, many apps will not require user intervention to determince the CD-ROM drive letter mapping if MSCDEX is present. I suppose you are blind to this since your product does not support the MSCDEX internal interface and you always have to manually intervene. Additionally, we provide tools for building automated batch files that will perform the determination of drive letter dynamically. This is a considerable boon for administering apps such as Computer Select on a large LAN. I will present an automated example of this later. BTW, Meridian Data is a direct competitor to both of us, and has its own agenda. 2) Applications that access the device driver directly are "archaic" since they do not work with your product? I would remind you that every copy of the the Microsoft Extensions in the world uses the industry standard "Microsoft Extensions Hardware Independent Device Driver Specification". Microsoft publishes the interface for both CD-ROM application developers and hardware manufacturers alike. You fail to see the validiy/necessity here on several points: a) Real-world, large apps (> ~7 disks, and many in the 30-40 disk category) are impractical or impossible with MSCDEX, or even NETX. b) RAM requirements for older machines, which still dominate the real world are an unfortunate evil. c) Performance critical apps can implement their own higly efficient, simplified file system without incurring the overhead of DOS and MSCDEX. Thses often look like a single large file when examined under MSCDEX. d) MDI rarely sees these apps since neither the interfaces or (often) the number of drives is supported by SCSI Express. 3) Really now, how useful is SCSI Express without NETX.COM or some equivalent network shell?
