Help with files

K so im kinda new at this i got an emulator and i tried to download pokemon platinum but when i do its under a .rar file and when i find the file for my emulator to play it doesnt want to find the file any advice?

You have to extract the .nds game from the .rar arcive , install winrarhttp://www.rarlab.com/

use 7Zip instead, it's better.

The user may choice it's own choice. Maybe it likes WinRAR better.
