Hi Charlie, If your primary requirement is to collect files, you should subscribe to the file upload plan 10gb, 100gb or 1tb. You will be able to increase the max file size to upto 1gb per file (depends on the plan), the number of files per file upload question, restrict file types, enable unlisted links to automate using Apps script or Zapier, add collaborators to provide access to specific users and use our addon to sync the uploaded files to your google drive. Restrict file types Login to Formfacade > click on the form to open it > Edit page will be displayed > In the Formfacade Edit page, click on the file upload question to select it > Question settings page will be displayed > click Answer > add the list of allowed extension types and click Save.
