You can use the following commands in the Pythonista 3 Python console to copy the folder back:
>>> import os, shutil >>> shutil.copytree(os.path.expanduser("~/Documents/foldername"), os.path.expanduser("~/../Documents/foldername"))where foldername is the name of the folder you want to copy (assuming that it's in the root of Pythonista 3's local files). You can also use shutil.move instead of shutil.copytree if you want to move the folder rather than copy it (which may be a good idea if it's very big).
By the way, is there any reason in particular why you're still using Pythonista 2? Pythonista 3 supports both Python 2 and 3, so there's generally no need for Pythonista 2 if you have Pythonista 3. In fact Pythonista 2 can no longer be bought on the App Store and won't receive any more updates.
