I’ve been experimenting with projects, but certainly don’t want to keep them. I’m unable to delete the unwanted files and cannot find any instructions in the manual or within the tutorials. I’m sure I’m missing the obvious. Please help
Welcome to the Forum
A Dorico project is just a file in the operating system with the extension .dorico at the end. You can simply deleted the file on disk.
If you want to remove the file from the hub, right click on the name and remove it from the list.
You can also find the files on your disk by right-clicking the icon in the Open Recent page of the Hub and choose Open Enclosing Folder from the menu.
