Richard,
The archive needs the extension .ARC (so it should be named
<filename.arc>) and if it's not in your current directory, you need to path it.
Example:
arc x df1:downloads/goodgame
That would extract files from an archive named goodgame.arc that is
presently located in drive df1: in a directory on that drive called downloads.
The files would be written to your current directory.
