I'm new to the internet. I have downloaded Disk Copy and Stuffit as SEA and HQX files from the internet via a pc. When I copy these files on to my mac they appear as pc documents and don't self extract when I double click.I've even tried using Binhex 5 and Suffit 1.5.1 to open these files.I'm not getting any joy!! Any suggestions would be helpful. Thanks in advance Malkit Tung.
