I just begin with VScode+platformio and i dont see
the menu “close project” and the good way to delete
Assuming you are using
Viscose VSCode, then File->close folder (or workspace) will close a project.
To delete one, open the containing folder and just delete it.
Alternatively, right-click on a project folder in the workspace / explorer and “Remove Folder from Workspace”.
thanks for your quick reply help
