Did you try archiving all the experiments and then deleting the project?

No, but I am able to delete other folder with experiements

However in this case the option is grayed out

Hi TrickyRaccoon92 , yes the examples folder is a special case, I'm not sure you can directly delete it.
Can you archive individual experiments in it ?

Hi AgitatedDove14 , I am also unable to archive the individual experiments in it.

It's not a major issue, but it would be nice to remove as some users may get confused.
