delete all saved scenes in lightwave

I know there are some lightwave users in zbrush so I will ask this question as I have not gotten a absolute answer in lightwave fourms. When I am in lightwave and save a scene, the scene gets saved among other saved scenes. I want to delete all the scenes I have saved in the past as the list gets bigger and bigger. When I open recent scene, I get a list of all the scenes I have saved, and I do not want those scenes anymore. What is the best way to delete them, I went to LW.CFG in my computer and deleted that files, but I still get those saved scene when I go to layout in lightwave, there must be a way to get rid of all the scenes I saved in the past other then going to LW9.cfg.
