The suggestion I have is to output the Full Compute Name in the beginning of the log file.
Thanks for sharing your ideas, I appreciate it! I am willing to write the name of the computer, but where can I find it? In the registry somewhere? Is there a system function that I can call?
Also if you can, at the end of a Defreg log put some extra lines or maybe a row of dashes to signify the end of the log before another one is started.
JkDefrag always deletes any old logfile when it is started. It does not append.
