in iOS, filepaths would access data only within the FM GO "sand box". You couldn't use one to access a file in Drive for example. You might manage something with a URL and a web viewer however. Not sure if it's possible, but that's the option I would investigate for such a need.
Phil, thanks, Thought it still not doable.
And yes, something can be managed with a URL and a browser, at least with Google Drive, However links/paths have to be managed manually. Not quite desirable !!!
