Where does bootable rescue USB store the log file for later offline viewing?

Once a very long scan has completed, where does Comodo store the results file for later viewing?

It took all night to scan and generate the report file. That’s OK. But where is the report file stored? Is it just in memory? So if I turn the machine off, I lose all the hours it took to generate it? Or is there some way to write it to a file on the USB?

Thank you.
