Hi Fellow Kindlers,

I am realtively new to the Kindle experience and this is my first post on this Forum, so please be patient with me as I am sure my questions have been asked and answered somewhere already.

I just can't find it.

My questions:

When I download a book using my Wi-fi I appear to get files in different formats installed on the Kindle.

These are:

.azw
.ea
.mbp
.phl
.mobi
.apnx
.eal
.txt

What exactly are these files?

I believe the format used by Amazon is .mobi.

Are all the other files necessary on the Kindle, or can I delete some or all of the non .mobi files and still read the books?

I have also downloaded a book from Amazon, '200 Halogen Recipes' but I cannot see a .mobi file for this book anywhere.

The only formats show in 'Properties' for this book are:

.azw
.ea
.mpb
.phl

I am sure there are many subscriber here who have the 'know-how' about these things so I would be really gratefull for their help.

Happy weekend everyone.

Cyril

I don't know the exact terminology, and there will be other people who can give you more accurate information, but .azw is 'similar' to .mobi and is Amazon's version of it, as far as I am aware.

All those files are necessary - no I don't understand why - but do not start deleting them! Books from Amazon are in azw format - which is a version of mobi.

Cyril, when you download a book the Kindle records the time and date, amends that every time you open the book, indexes the book so that if you search for a word it will already know all the locations where that occurs, will record bookmarks, highlights etc., and most of those things will be stored using different file types. I'm sure a google search will reveal the exact purpose of them but it's not something you need be concerned about. They take up very little space.

Incidentally, I like The Everyday Halogen Oven Cookbook as it works particularly well on the Kindle and gives all the basics.

Actually, I don't think anyone has asked that question before.

I think someone once decided to 'tidy up' their Kindle and deleted all the files they didn't understand. I think they had to have a new Kindle :-)

Thomas Hardy says:
hi Plutus, you're correct about the .mobi format the files you list are all components of the book you download. So don't be tempted to delete any, as an example, all web pages will consist of many files and in different formats for images and links etc. when an author compiles their book for kindle it may consist of many files including the cover image,
Apart from the risk of disabling your kindle it could also make your kindle warranty invalid,
A friend recently decided to remove all .dll files from her computer as she is interested in numerology and thought they were unlucky, she was quite surprised when her new £500 computer stopped working,
sounds funny but illustrates an important point,
good luck with your new kindle I'm sure you'll enjoy it as much as we all do

Oh dear - removing dll files from a computer - not good.

Highwayman says:
The only file you actually need from amazon is the .azw

If you are downloading from other sources you often get other files but again you only actually need the azw or the mobi file. However most of the files are small so why worry. If you want to experiment then just copy the files to a pc before deleting. I did post an explanation of most extensions here but it was probably 18 months ago.

TH, I'll be using that one as an example of the silliness of superstition for a long time to come!

I have been sat here for the past 5 minutes trying to figure out why she thought .ddl unlucky - knowing absolutely tad all about numerology I've drawn a blank. Can anybody put me out of my misery? :-)

Hippocratia says:
Well, I've just looked at Wikipedia on numerology and can say the following:

dll = 433 = 4+3+3 = 10 = 1+0 = 1. Why 1 is unlucky, I don't know, however apparently it can mean: 1. Individual. Aggressor. Self. Leadership Yang.

Berzelius says:
As Highwayman says, the only essential file is the azw one. If you delete any others then you are only likely to lose such things as notes

Oh dear, Amazon seem to have decapitated my post, hence the abrupt end!

Hippocratia says:
However, if you've gone to the trouble to make notes it would seem rather pointless to delete the files.

Many thanks to you all for your replies. They were all extremely enlightening (even the ones on Numerology (LoL)).

I am certainly aware .dll files and the like are extrremely important to the OS and I would never delete them. I deel so sorry for Thomas Hasrdy's friend who deleted all their .dll files.

My post was not really about other files on my PC, only those which are downloaded onto the Kindle when I purchase a book from Amazon, Gutenberg etc.

I have discovered that some files have been created by Amazon themselves in order to ensure that books are only readable on the Kindle.

I agree with Berzelius that once you have typed a few lines in the 'Reply' box it appears to go haywire.

Thanks again to you all for your responses.

Cyril
