How can I import a custom map into Minecraft?

Okay, follow along with me:

1. Go to the downloaded map or whatever, and if you have it in a .ZIP file extract it using WinRAR to a specified folder (I would recommend your documents folder). If you don't then go to the folder where the file was downloaded too, and continue on
2. Cut the extracted file
3. Go to your search bar, and type in run. Click the application "Run", and inside of run type in %appdata%
4. Open up the folder called .minecraft
5. Inside of that folder, open up the folder called saves
6. Paste the file you cut in the beginning into that folder

Boom! You are done!

EDIT: JonK posted this method:

1. Follow the first two steps above
2. Open up the current Minecraft Launcher
3. Go to the Edit Profiles Button
4. Select Open Game Dir
5. Then go into saves
6. Paste the file
