I have been following the "Building Your Own Modpack" tutorial but when it came to archiving the files in the minecraft.jar and putting them into a modpack.jar I came into a slight problem.
I selected all the files in the modpack.jar (Opened with WinRAR) and clicked add to archive and then a window pops up asking me what files to archive. I saw nothing like this in the tutorial and I thought that the files I selected would be the ones archived and not any extra steps. I could click the minecraft.jar in the pop up but I don't want it to put the minecraft.jar in my modpack.jar (A little confusing?). I want to completely avoid redistributing it, that's all. Sorry if it's hard to understand what I mean.
Edit: Sorry, I didn't realize lukeb28 had a more clear guide on the forums, I fixed my problem.
