Ok. The Zip file is named MyShaders. If you extract it, you got a folder which is named MyShaders too - and inside it, you have two folders ; one for the shaders, one for the scripts :/
Finally. I notice that you downloaded nine times this Zip file. So you have somewhere on your computer nine Zip files which are just useless :/ If you need help trying to understand some shaders, let me know. Have fun ++
