Can I make a form where the respondent is able to upload a file attachment?

In addition to a registration form, I would like to be able to have reposndents upload a file with their application, ie: CV. Is this possible with your software?

Yes, that is possible here in JotForm. You need to add the File Upload field to your form in order for the user to upload the file to your form. Here's a guide: https://www.jotform.com/help/332-How-to-Create-File-Upload-Forms
