Getting files from Minotaur to chip

[GTS]

So I wrote my first program, got my burner up and running, go to burn the chip and when I go to the file where I saved my new program it doesn't come up in the list of files I can write to the chip. Looking at the files Bill sent me they say .225K at the end of the file name. This leads me to believe I may need to convert the file somehow??? What do I need to do to make it so that the file willl come up in the list to write to the chip?

I'm so close to getting my first file in the truck I can taste it!! I just keep running into these little snags!! It's killing me!
