AZW is a renamed MOBI file. PRC is an older version of MOBI, renamed to work on a PALM reader. Both are valid alternative extensions for MOBI, and are supported as such, PRC because people might still have some, so why not recognize them properly, and AZW because it is used specifically to refer to Amazon-purchased MOBIs, which may have DRM.
HTMLZ is a DeDRMed
Topaz ebook (TPZ if downloaded from browser, AZW1 if downloaded via the ereader). It is a failed experiment that is fortunately rare, and only a few books should still be in that format. The only one I ever saw was a library loan of
The Princess Bride, which oddly seems to be a very old edition that the Kindle Store doesn't sell, but which is still somehow linked to OverDrive.
So that leaves two Amazon formats: AZW3 and MOBI... just like I said.
If you are wondering why the Kindle can
read so many formats, (in which case you have forgotten to mention PDF, TXT, and HTML.txt,) it is not alone in that respect...
