I wanted to combine three different texture packs, but if I want to paste it into the other folder, it just will not work. I have already looked on Youtube but it will not work. I always press copy but I can't paste.
Can you define that a bit more accurately?
What's wrong, what program do you use?
Simply inserting all into one another can't work at all. If you want to use all at once, just select all 3 in Minecraft.
