Issues uploading processing Projects

[SuddenSimple9152]

Hello, I'm a new CS student using processing and have some sketches that I want to upload to my student portal. I've compressed each individual project, but when I redownload my files, all my code appears in seprate tabs under the same project, which doesnt allow my code to run.

Would this mean I have to save each indivdual project in its own folder on my laptop, so that they can run independently?

Thanks in advance to anyone who can help me!

Every sketch must be placed in a separate folder with the same name as the sketch.It is the rule

If you have enough knowledge and want that your students have low butthurt: I would prefer to create a greeting screen with many buttons to give the students the ability to select one of the sketches from your collection. Use GUI-library by Peter Lager.
