Open Subfolder for Mac & Windows
Open Subfolder is a contextual menu extension for Mac OS and Windows which adds the ability to open a folder located inside of the currently selected folder.
To use the extension, select a folder and open the contextual menu for it. (Control-click for Mac OS. Right-click for Windows.) If the selected folder contains one or more folders, these folders will be listed in a submenu attached to a new menu item in the contextual menu entitled "Open Subfolder". In addition, if those folders listed also contain folders, their menu items will also have submenus attached containing a list of folders contained within them. If you select one of those menu items, the folder with that name will be opened on the desktop.
