how do i veiw the tutorials?

i downloaded a tutorial from the unity website about building 3rd person games. and i have no idea what program to use to view them. what do i do?

Try using VLC

Do you mean the .zip files?

You need to download an extraction software, like this. After you install it, simply right-click on the downloaded file, and select extract to “Tutorial Name”. This will create a folder in the same directory where you downloaded the .zip file to.
