"DO NOT USE THIS"
None since it was not able to unlock a file or tell me who had the lock on it (reboot fixed the problem).
After downloading this program discovered it had automatically installed some software to hijack browser links that would pop up with a link the yellowpages. Running malwarebytes found Unlocker had added this software in the registry.
Essentially unlocker installs malware. DO NOT USE THIS. There are probably other apps that do the same thing.
