How do I access my Minecraft files to download a texture pack?

I want to install the paimterly pack, but when i click on the minecraft file so i can get to the textures stuff, all it does is run the game. I have ver. 1.0 and it's saved as minecraft.exe if that matters

 Ansver:

They're in this folder:

C:\Users\[user account name]\AppData\Roaming\.minecraft\ texturepacks

There's a button in the game to open this folder for you. Click 'Texture packs' and then 'Open texture pack folder'

 Ansver:

First, go into the folder titled %appdata% from the start menu. Go into the roaming folder and then into the .minecraft folder. There is a folder inside there titled "texturepacks". Copy the zip file into there. Open Minecraft. Go into the mods and texture packs section and click on the texture pack.

 Ansver:

What you need to do is first open up the start menu. Then search for %appdata% and click on Roaming. Open up the .minecraft folder. Once inside you should see a folder labeled texture packs. Drag the Painterly Pack folder into this folder and that should install the texture pack. Close all the windows and run minecraft.
