This like my 3rd thread tonight. :D

Anyway I was looking through ES File Explorer and I notice that books are not in AZW that we all have come to know or even in Mobi for that matter but on the Fire they have the extension PRC :eek:

I have to wonder why Amazon chose to go back to PRC or do you think this is a newer format then then the old mobipocket format?

'Tis the same with Kindle for Android (except for sideloaded stuff).

The format didn't change. The extension did. This prc is not the Palm format, it is one of the extensions for a container used by the Mobipocket format.

prc, mobi, azw are all interchangeable on the Kindle. See http://www.amazon.com/gp/help/customer/display.html?nodeId=200140600

Interesting. I think mobi was an offshoot somehow of prc back in the day - maybe it was the encrypted version? I barely remember that whole scene. Those were the early days of ebooks, to be sure.

I'm curious if any KF8 books have been released yet?

Yes the early days indeed. I have several PRC books still but if it's been that way in the stock Android app then I guess it's been that way for a long time. I nevered noticed it till now.

A PRC file is simply a container - it can contain data in any format whatsoever. Mobipocket has always used a PRC container, but a PRC file doesn't have to contain data that's in Mobipocket format - it can contain anything at all. There's an 8-character "tag field" near the start of the file which says what type of data the file contains; for a Mobipocket book this contains the string "BOOKMOBI". You can see it if you open the file in Notepad or some other text editor.
