hl2

In the srcds folder, what is the point of the hl2 folder? This is something I've always wanted to know!!!

This is the folder that contains Half-Life 2 specific textures, models, sounds and a lot more. Almost every mod uses material that is developed by Half-Life (even a barrel in CS:S is from Half-Life 2). This is why every installation gets a HL2 folder, so people can use the Half-Life 2 content without worrying about the client not having it.
