Uh, no, actually, as explained in many topics, people buy a project. So once they paid for your assets, they have access to any files you upload to the page, in perpetuity. And you don't need to delete the file first, you can simply overwrite it. If there's no more room, you can ask support for a quota increase. Hope this helps.
