CSS Steam Dedicated Server

[tonyfordz]

I wanted to ask where it is that you need to place maps for the default dedicated software that steam gives its users. I have yet to be able to find anything online that tells where to place maps in order for them to show up in the dedicated servers list & I would like to add some maps in which I have made myself & remove the default maps that comes with the game. Does anyone know the path in which I need to place my files & also how to remove the default stock maps so that only my maps show up in the server list? If someone could also be nice enough to give the HL2 Death match locations in which custom maps need to be placed would also be grateful.

Thank you guys,
Tony Ford
