Don't know how to install Resource packs? Or maybe there's an EPIC adventure map/mini game you want to play, but you just can't figure out how to install it? Fret no more Minecraft Extra Tools allows you to do those very things!

Maps:
Unzip the folder
Click "Install Map"
Locate the Unzipped Folder and Select
If no errors, you should be good to go. (Open Minecraft and play!)

Resource Packs:
Click "Install Resource Pack"
Locate the Pack you wish to insert.
If no errors, you should be able to enable it in Minecraft.

Creating a new instance:
Click "Locate Minecraft path"
Locate your minecraft.exe or minecraft.jar
click "Create new instance" and wallah!

(this is good for mods or creating a new YT series or such)

If anything comes to be leave a comment!
NOTE: Works for all Windows, except for XP.
Won't work for Mac, or linux.
I plan to add more features, so comment Ideas!
