What's the difference between Google file upload and Formfacade HTML file upload?
Google Form's file upload question requires your users to be signed in to a Google account to upload their file and submit their response. The files are uploaded to the form creator's Google Drive.
Formfacade converts the Google file upload into a HTML file upload. The users will be able to upload a file using the upload file button and submit the form without having to sign in with a Google account. In the Google form, the file upload question will be converted in to a short answer question, where the url location of file uploaded by the user will be displayed.
