It's been awhile since I've visited and I did a search but was unable 
to find an answer.  Is there a utility that will convert *.fil files 
back to *.mid files?  I cannot play the .fil on my PC and would like 
to convert some to midi's.  I have the Giebler utilities but don't 
recall if they can do that or if they will even run under Windows XP.

Any advice will be appreciated.  Thanks.
