Thanks for the reply, it cleared things up. I've 2 other questions. This may sound stupid, but i didn't find the option to change the language metadata into spanish in the mobi2mobi gui(VB7 w mobiperl 0.43-win). Am i overlooking anything? If not so are there any other way to change it?
Also is there another way to recognize whether a particular prc/mobi file is a dictionary other than the one involving hex lookup as mentioned in this thread?
