Then I had an epiphany, after a conversation with one of our very nice and helpful Network Admins (no sarcasm, our people defy and trample the stereotype) I realized that my link was pointing to the root of the SharePoint. Since SharePoint uses WebDAV you should be able to get it to work inside of GoodReader however I simply could not get it to work and even my emails to GoodReader support didn't help. I have sung it's praises before ( here and here) and will do so again*. Mostly I use it for archiving, reading, and annotating PDFs. While using my iPad I use GoodReader a lot. I think that the reason the Mobile Documents folder is in the invisible Library folder is that Apple expects that most developers for the iOS platform will have corresponding OS X apps that access that folder for you.GoodReader and SharePoint and OneDrive (business) But GoodReader Help files say that you can add or change things in their folder, which looks like 'RANdomCRAP~com~goodiware~GoodReader'. I would not mess with those unless you are certain Apple allows it. That folder will have a number of folders for any iCloud apps, including Pages, Numbers, and Keynote. Then find the Mobile Documents folder in the Library folder. Then type in '~/Library' (without the quotes) and click 'Go'

The invisible Library folder can be accessed by going opening a new Finder window and clicking on 'Finder/Go/Go to Folder.' in the Finder window But I installed a shortcut on my desktop by opening the library folder and Command-Option-Dragging the Mobile Documents folder to my desktop.

In fact, the folder is inside the Library folder, which is invisible (at least on OS X Lion).
