How can I force Calibre to use a certain format for conversion?
I have 2 formats in a file - pdf and prc. I would like to convert the prc to mobi (I know, it is the same thing, but I want it to read mobi. That is OCD for ya). Is there a way to force Calibre to "convert" the prc file, or do I have to remove the pdf version, convert the prc and then move the pdf back?
