Delete Project Folder - Trial Version

Hi. I am trying to delete a project folder in a trial version of your software but I keep getting an error message saying “Only empty folders can be deleted. To delete this folder first remove all items within it”.
How do I delete all the items ?

If you click on the three dots to the right of each items name, you will be able to delete each item individually and then the folder.

What if you don’t have three dots? Check the Explorer Account.
