With Formplus, you can receive files of any size and type via your form(s). There is also no limit to the number of files that can be received on a form.
To allow your form users to upload files on your forms, add a file upload field to your form when creating a form or editing an existing form. In the form builder, there is a File Upload section, click or drag the field, then drop the field to the builder pane.
Click the edit icon to edit the field name or help-text. Make the field a required field to make respondents unable to submit until they upload the file requested, you can restrict the type and/or size of files that can be uploaded, and you can also automatically rename all files uploaded with data from another field.
