-- A question about using CF card on Visor! (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=13646)

I used install ebooks(pdb file) via Palmdesktop,
last night I copy some .pdb files into CF card
on my pc using a cf adapter, and then copy them form
CF card to my Visor Deluxe via the Innopocket flashadapter.
but I cannot open them on Visor.
I remember I did this for .prc files and it works?

What could be the problem?

Thanks!!
