Elaborate bytes applications shout for it if it is not in the system32 directory. However, even when I had a version the shouting continued.

It is installed by Slysoft's CloneCD software. And, if you delete the file, your drive doesn't work anymore. But if you uninstal CloneCD, it will start working again.
why not ask Slysoft, Inc. about it? It's their driver!

Best practices for resolving ElbyCDFL issues

A clean and tidy computer is the key requirement for avoiding problems with ElbyCDFL. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
