Question about mobipocket file output. I discovered that the reason I couldn't use mobi files produced by Calibre on my PDA is that they're .mobi files instead of .prc. When I renamed them to .prc, they worked. So I put in a ticket asking if .prc could be an output option in Calibre. Kovid answered that .prc is a deprecated extension in Mobipocket, and that Calibre wouldn't support it.

This was the first I'd heard that, so I'm just asking for more information. As far as I can tell, I have the most recent version of Mobi Creator (4.2), and it produces .prc files. Soooo....how is it that .prc is deprecated in mobipocket?

My Mobi Reader (desktop) can read either .prc or .mobi. But my older (Win CE) Pocket PC, which also has the most recent version it can support, can only read .prc.

I take it that there's more to it than just choosing a different file extension, which is why Kovid doesn't want to add .prc output as an option. But if a .mobi file renamed to .prc works as a .prc, wouldn't adding the extension option be a pretty easy thing?

I don't know, mind you, I'm just wondering out loud.
