GoodReader vs OneDrive for Business vs DropBox

OK, not really a vs, but my new boss previously used GoodReader and Dropbox to sync all files in a folder on to her iPad.  We use Office 365, so in terms of keeping data 'within the organisation', I was hoping to do the same using OneDrive for Business, instead of GoodReader / DropBox

- Is there a way to download all files in a OneDrive for Business folder? (instead of downloading each file individually)

- Can GoodReader sync with OneDrive for Business? (SkyDrive Pro)  Can't find anything to suggest this

Thanks!
