Can downloaded games be used on an Amiga?

[tormedhammaren]

Hi Every1,
I have just brought an Amiga A500+ I have a game I wanted to play on it but the disk is corrupted. I've found a download of the same game on the web, but the game is a ADF file? Can this download be used with my Amiga? And also how do I put the file on a disk? does it need any booting software on the disk as well?

Many Thanks
