I highly recommend purchasing an external SD card for your Crestron processor. They’re cheap and will increase the lifespan of the flash memory built into the processor. This one was only $10!
You can even setup logging to write to it instead:
> FORMAT > RMLOGERR ON NOTICE > RMLOGERR RMLOGERR status: Current Log State is ON Current Log Name is /rm/RMLOGS/Crestron_00.log Current Size is 262144 Current Number of files is 1
