Use the following URL to access the files on the USB medium by using the HTTP server in the LCOS:
http://<Device-IP-Address>/filesrv/<Mounting-Point>/<File>
If, for example, the file is named coupon.jpeg and it is stored in the base directory \public_html of the only USB medium, then you can access it with the following link:
http://<Device-IP-Address>/filesrv/usb/coupon.jpeg
Note: Files can be accessed with HTTPS as well as HTTP.
