This command changes the root data directory to the root of the SD card. In order to execute a RootDir On command you must enable it in the setting from the main console (menu->settings). If a RootDir On is executed and it has not been enabled an error will occur. Executing a RootDir Off will change the root data directory to Mintoris.Basic/Data. The current working directory is reset when a RootDir command is executed.
Use caution when with this option. By allowing access to the entire SD card it becomes possible to delete or damage files not related to Basic.
