Dear Scott,
Fantastic. It works fine.
Only I need the way to copy the file from the URL your plugin provide to known folder into the app.
I have an URL like this:
file:///private/var/mobile/Containers/Data/Application/9BC87323-B20C-4754-8DEB-5AE986EBD4C7/tmp/es.cnksoftware.myapplication-Inbox/ImportedFile%202.zip
I have no subfolder into Documents… Must I get the file using LFS for example?
I will continue testing and let you all know.
thanks so much dear Scott,
Yes there is a good example here,

Dear Scott,
Only 1 little doubt.
For iOS 11, the uri need to be encoded ?
The sample code is as follow:
if( iOSVersion \>= 11 and system.getInfo("platform") == "ios" ) then local json = require ('json') native.showAlert( "File Imported", json.encode( ev.urls ),{"Ok"} ) else native.showAlert( "File Imported", ev.url,{"Ok"} ) end
I suppose from iOS 11, more than 1 uri can be returned and it is returned in event.urls.
My question is: why to use json.encode and not json.decode to decode the uri ?
Thanks again dear,
event.urls returns an array of strings. In order to display the array I convert it to json. I have not done full tests with iOS 11, I am still waiting for the full launch.
Ok dear. Thanks again.
I’m using this code to get the file. It works fine for the iOS 10…

I needed to use decode URI function to decode URL type like %20 for spaces… If not use it, the file like “documents merged.txt” will be “documents%20merged.txt” …
