To be honest, I’m a bit surprised this is the first time I’ve made a mess of it like this.

FWIW, a good practice is to always include a README.TXT file in your ZIP archive which provides a table-of-contents for the supplied files. All the fabs I’ve worked with will look at that file and alert you if there’s then something missing from the ZIP archive. So, as long as you get the TOC right and then use it as your template, you then have an additional “safety” on mistakes.

I’ve included a sample README.TXT file.
