@dgelessus Thanks!!
I still couldn't see the Pythonista 3 folder from Windows, but I hadn't tried sharing via iCloud, only DropBox and that didn't give me the File Import option from Pythonista.
Doing it from my iCloud drive works - it imported fine and I was able to extract it to a folder and then run it :)
I did have to run it using version 2.7 of Python, otherwise I got an error, but that is a different issue :)
Thanks mate!!
cheers,
Paul
