I don't even have a Nexus 7 yet, but I expect to get one in 19 days and would like to get ready.

I expect to be using ebooks and music (mp3 files) that I already have, rather than buy from Google Play, but wonder how I can side load them, and whether what app I use to read or hear them will be able to find them.

On an iPad2 if I want to see how one of the ebooks I have designed looks in iPad, Bluefire, and Marvin I have to load the ebook three times, once through each app. So far as I know once it's in the iBooks 'folder' there is no way to get to that ebook with one of the other apps without loading it through that app - in which case I have three copies of the same ebook on my iPad2.

Is it the same with a Nexus 7? If I want to check how an ebook looks on the Sony Android reader and with Moon+ and with the native Google ereader, and so on, will I have to load them through each individual reader? Or is there a way of loading an ebook into one 'folder' and then accessing that one ebook with any of the ereader apps I have on the Nexus?

Will I be able to set up folders myself on the Nexus? If so, how do I do that?

How does one side load ones own ebooks to a Nexus anyway?

Thanks in advance for any advice, or pointers to where I can get the information. I'll probably have more questions still, so thanks in advance for your patience.
