Thx for the reply so let me understand, as I may have explained wrong or you may have misinterpreted.
I have the .mobi file which I want to unpack, it has the .mobi extension, its in the attached.
I need to unpack this ( as I do not have the original files only the mobi)
First, what do I use to unpack?
I tried Calibre, it allows me to import the mobi but it will only allow me to convert. So what do I convert the .mobi to?
