I am experiencing a problem launching applications (not music files) after downloading. They show up as blank documents.. I need to re-name them with the correct extension, (such as .mp3 on a music file)? I don't know what extension should be put at the end of a particular graphic application to make it launch (Quark Express).

At the end of music files you put .mp3 and they turn into a real player file and can be launched. What should be done differently with application files such as Adobe Photoshop or Quark Express...?

I am running Mac G3 0S9.2. Any help out there??

Thanks
