 the `userDefineLang\` subfolder can be placed there as well, though it won't be created by default when the Cloud settings folder is first populated).
 
 If the Cloud directory is enabled, that will take priority over the portable or standard config file location; if `doLocalConf.xml` is present, it will take priority over the `%AppData%\Notepad++\` folder; if neither are active, then the standard config file location is `%AppData%\Notepad++\`.
