oh no you got me misunderstood.. that just meant that i think I'm in a little bit of a trouble not being able to view the sub directories. I will ask the vinculum's customer support about this matter, and for the mean time i will be concentrating on the files located on the root..i wasn't successful the first time i interfaced the vdip2 to the pic16f877a. I could not get any response from the vdip. all i get are weird characters printed in the lcd even when the vdip is turned off. have you encountered this?
