I have a number of EPUBs that I manage manually i.e. they are not in a Calibre library. These are in a Google Drive folder so Calibre is simply not an option.
I'd like an easy way to convert these EPUBs to MOBI and send them to Kindle via USB, on demand. This functionality is present in Calibre and it seems to me these should not be tied to the Calibre UI; so is there a way to do this via a script or something?
If this is a tall order, just conversion is still fine, I can manually drop the files in the Kindle after mounting it via USB.
I'm working with Windows 10 64-bit and a brand new Kindle Paperwhite.
