In the world of Windows (and its DOS legacy) files were generally the starting point. In iOS it's just the opposite. Whatever you're going to do it will start with an app. Within that app you will have saved files. So instead of finding an .xls file, double clicking on it to open a program as you would in Windows, you open the app, then open the file. Unlike Windows you won't find files listed that cannot be opened with that app (unless you accidentally saved them there).

I have a question - If I have an ebook in epub format that I've opened with iBook, then iBook knows where it is. Then maybe I find another ebook reader and open the same ebook with it & it also knows where the ebook. With Apples system, of course I don't have a clue & will have to import it again. So does Apple then have two separate copies of the ebook or is the iOS smart enough to know it already has that ebook, create a pointer to the it and 'share' the location?
It seems more likely that I'd end up with two copies since I would be importing the ebook anew from a location I know (e.g. my Dropbox). But if I knew where Apple put the file then 'I' could point the second ereader SW to that location, thus saving memory space.
As others have mentioned, if you want to save a file to more than one app, then yes, you would have more than one copy. That would apply to epub, .pdf files, etc. The fact is that you're almost certainly going to settle on one app to do what you want so I guess I don't see that as being a real concern.
I'm a little confused as to why you would want to "work on" a file in more than one app. Even though one file might work with more than one app you shouldn't assume it would be the same experience or that you'd end up with the same results. That's no different on an iPad than on a computer.This is just an example. Many file types can be worked on by more than one program (or app). How would the second app know where the file is?
Although MS Word and Apple's Pages are both word processors, they are two different programs. Apple's Pages is much more accommodating when it comes to opening and saving MS Word files than the other way around, but in the end they are different programs and handle files in different ways. It's no different with apps on the iPad. You shouldn't expect to "work" on a file in multiple apps.
Like any computer, you should pick a program/app you want to use and use that exclusively. If at some point a better app comes along, just as on a computer, you'd need to import your files into the new program, make adjustments if needed and then archive or delete the old files and start using the new app.
Or am I missing your point completely? (Wouldn't be the first time )
