I am trying to get my kindle books into an old version of kindle that i have just installed and I'm confused by amazon's listing of my 'kindle devices'.

I thought that meant hardware devices - ie computers and/or smartphones.

But i can't find any description of what it means.

I just find 10 'devices' listed. And 'edit' devices just allows changing the name is all.

I don't have 10 computers.

I need to deregister some 'devices' because I've been told from time to time I can't download a book because it's on too many devices.

But what does that mean if I do that? I lose nothing? Wherever those books are they'll remain there in some kindle directory somewhere but I'll just not be able to download any more to that directory or something?

i.e. there's no risk of any kind in deregistering a 'device' ?

And it all might be spurious anyway? I mean it's a question of what amazon thinks rather than what I've got? I mean all those previous 'devices' ( simply directories on machines) might have crashed and burned long ago, may simply not exist?

There seems to be no way to identify which directory on which machine a 'device' belongs to.

Can it be explained to me?
