The issue is coming up as a result of trying to share documents between my mobile and my PC. On the mobile, the document is being created - and at present the easiest way to create the file to save to google drive has been as a google doc. But then I need to use it on the desktop later, so I need the file in docx format there. I don't want to potentially start creating several thousand unnecessary google documents and lose formatting/other information by testing it on the directory tree to be synced, so I wanted to check my understanding first.
