gs shrink--gs/os recognition & wav startup sound question

["AMart79196@gmail.com" <AMart79196@gmail.com>]

I have a old scsi drive that I had connected to my IIgs way back when
and I had customized it quite a bit.
I would like my current setup of GS/OS 6.0.1 to be able to recognize a
SHK or BXY file and if I double click on them have them automatically
run gsshrinkit.  This is probably a super simple fix, but I am drawing
a blank on how to get gs shrinkit inter-grated with gs/OS.

The other question was having to do with the startup sound.
I know that the WAVE format is what is needed to play a song, but, I
am having no luck making this happen.  I put a Wave formatted short
400k song on my CF card (i used cider-press and added the file to my
volume) and when I tried to select it, it would not show up in gs/os.
Any suggestions??  I know that I was able to do it another time in the
past with another wav file I xfered over 11 years ago, but i just
can't remember what I did back then to make it work.

Thanks guys
