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 per form.
To allow your form users to upload files on your forms, simply 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 File Upload field, then drop the file upload field to the builder pane.
Click the edit icon to edit the field name or help-text. You can make the field a required field so respondents are 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.
