Effect

Changes the active folder inside the virtual USB device or the storage device connected to the USB port of the Rookie Drive.

Syntaxes

• CALL USBCD ("<Directory>")

Only with storage devices:

• CALL USBCD ("<Directory>/<Directory>") - Changes to the specified directory, relative to the current one.
• CALL USBCD("/<Directory>/<Directory>") - Changes to the specified absolute directory. Note that the difference is an extra slash at the beginning of the specified directory chain.

Parameter

<Directory> is the name of the directory on the USB device. When omitted with a storage device, the name of the current active directory will be displayed.

Notes for storage devices:

• Changing the current directory will unmount the currently mounted file, this is due to a limitation on how the underlying USB controller hardware works.

• An alternative way to change the current directory (without mounting any file) is to go to the boot menu, enter the desired directory, and then pressing SHIFT + ESC (ESC alone will restore the previous directory and mounted file).

Examples

CALL USBCD ("GAMES")  'Changes to the GAMES directory

CALL USBCD ("..") 'Changes to the previous directory
