Subject  :  xxcopy as backup utility - Nero, DirectCD
Size(KB) :  2


Hi Kan,

I'm sure you have heard that Win XP will have built-in support for CDRW. I
read on the alt.comp.periphs.cdr newsgroup that XP simply will include
stripped down versions of Easy CD Creator and DirectCD - licensed from Roxio
(just spun off from Adaptec).

I recently purchased ECDC 5 Platinum - one of the attractions was that
DirectCD has some kind of compression built into it. Haven't tried it yet.

I was hoping for something that would allow us to use CDRWs just like we use
floppies (bootable, readable from any Safe mode, etc. etc.)
