Just use
(startapp "notepad.exe" (strcat file "\\SheetIndex.txt"))

Thanks, this puppy made a bobo, Iused the wrong var. I should have used folder in lieu of file.
Both ways now work. I have properly cleaned up after myself.
file was set to : (setq file (open (strcat folder "\\SheetIndex.txt") "w"))
I should have used folder varable. That was why I was getting the internal error.
