Downloaded a texture pack,now it won't stop crashing

What seems to have happened is I downloaded a new texture pack,I clicked to use it,it crashes,after a couple attempts,I realize that this is the problem,but the game crashes before I can change anything,I search online for a solution,and it says that I should delete the texture pack from the minecraft file. But I don't see a file like this,all I see is the minecraft application in my downloaded files. So I don't know what I can do to resolve this problem.

Steps to Reproduce:
1. Download GrungeBDcraft texture pack
2. Run Minecraft at 1.7.2
3. Use said texture pack
4. Crash over and over
