Where on my computer would a minecraft texture pack be saved?

I downloaded a minecraft texture pack and moved it to the folder that opens up when u click on the mods and texture pack thing on the menu. Now the texture pack has made minecraft stop working right and i need to find the folder where the texture pack is saved so i can delete it. I would just go to the mods and texture pack thing on the menu but every time i launch minecraft the thing just freezes up.
