USNO A2.0 and Guide8

Hi!
I've downloaded USNO A2.0 (~6 GB!!!).
Now it's on the hard-disk.
I cannot burn DVDs, but only CDs.
Is it possible tu use this cataloge in Guide8 without bunrn it on a disk??
Can I use it directly from a directory in my hd?
In menu "extras" (Guide8) there is only dhe link to download data from
internet or from a CDrom.
How can I do?
Thank you in advance.
Ciao

PS: sorry for my bad English :-)
