If you're using it, if you actually paid for it, you'd best know what you're using. (What does Cocktail Help have to say about the functionality?)
I don't use any program I haven't paid for.
The Help file has a two sentence description of what a Preference is and then goes on to say: "With Cocktail's search tool one can search for corrupted preference files with ease." It then says you will be able to reveal the file in Finder or move it to Trash, followed by a caution that corrupted files can cause problems.
Clearly, none of the information is aimed at anyone with in-depth knowledge, which suggests to me that an unenlightened user should feel confident that the program is doing as much as can be done. It would be more helpful to say: "By the way, you can run this test but still have a corrupted Preference file. We suggest...."
Joemike's information was much more useful.
You are probably right, it is just another line in the resume.
