Hi Theo, and thanks for contributing! How to upload new versions of files: under the download link in every file entry, there is a small number (for instance, #55441). If you click on that, you will be taken to a page which has a link titled 'Upload a new version of this file'. If you go to that page and follow the instructions, you can just replace the existing file without having to delete the old one or create a new page.
