This add-on extends the functionality of the premium Wordpress plugin Gravity Forms. It allows to add a new single file upload field that is not related to the WP media core. Yes, you will not find the loaded file inside the media manager, also it uses a different folder for every location (based on form id, field id and entry id). Also, you can activate the option to let user upload more than 1 file!!!
