You double-click, check the extraction options you want, and poof! you get an ascii model and all of the relevant textures in one shot.
unless there is a setting I've missed Fred anytime I double click a mdl file it only extracts the tga, txi and a ascii-mdl. however it doesn't automatically extract the mdl & mdx for me. I have to extract those seperately.
