Removing unused library from library folder

I want to use Henning Karlsons library for the DS3231 real time clock. He is from Rinky Dink Electronics. I have somehow got the folder into my examples folder. When I try to compile it I get the answer this folder already exists. In the manage libraries list there is a library from Wicket, Ayers, Wippler, Nth Widget for a DS3231. I believe this to be the offending library. I have uninstalled it but it is still there. I can find no way to remove it.
Does anybody know how to remove it? It may also be necessary to remove other libraries with the same name from the list. The Henning folder is definitely not in the manage libraries list. If it was it would show the author.
