I want to create log file from can messages while Lexia connected to obd, but many message has dropped. My sd card is too slow to write all data?

I start logging with can log crtd /sd/lexia.crtd command

Closing log: Type:crtd; Path:'/sd/lexia.crtd'; Filter:off; Vehicle:MI;

Statistics: total messages: 3334194, dropped: 2707476 = 81.2%

In can log i can see the incoming messages?

This is a RX message:

175594.785 1R11 346 27 10 40 00 00 00 00 42

if 1R11 is 1T11 this is a TX message on CAN1?

How can i download the log file, the easiest way, because if i use browser and add the file url (ip/lexia.crtd) the browser load its content.
