The Directories->Zip menu item will activate a Zip Directory dialog with the current selected directory as the source directory. This dialog enables the user to click in the full target path and edit the target zip file name, or the user may manually enter the full target path and file name for the target zip file. Zip option switches may also be set from the dialog which allow for zipping only the selected directory or the selected directory branch.
