The Xfce file manager, Thunar (4.18 with en-US as language), also has “Create Folder…” under the File menu, and in some contexts in the right-click menu.
Under Preferences, Behavior, it has both “directory” and “folders”.
man ls uses “directory” only tho, and of course mkdir.
In KDE, when right-click menu gives you an option for a new “folder”. I will call it a folder.
