so far, at least, .prc files are working just fine on my kindle. does mobi2mobi not do prc to prc 'conversions?' all i really want is to mess with the title, author, etc, not to actually convert to any other type of ebook, if it's not needed.
i'll play around with it and see what i can manage to figure out. thanks for the pointer to the command prompt and the example!
EDIT: thanks sooo much! it's working wonderfully for .prc to .prc, making all of the changes i wanted, and still easily usable in mobipocket reader... i haven't tried the new files on my kindle yet, but i will shortly.
one more question (you knew there had to be more, right??) -- is there any way to copy/paste into a command prompt? i'm assuming not, yet hoping so, lol.
