I did that, on normal minecraft it comes up with a window where you can select the .zip files and add them. But for that I have a Minecraft folder with all the mods, stats, etc. But I don't have it for tekkie, which needs a separate one.
Right just downloaded and got technic finally up and running. Wanted to have the texture pack from Yogscast tekkit series, but I don't have a folder in Application Support for Tekkit or Technic so I can't add the texture pack to my texturepack folder... what am I meant to do?
