pkt2qwk appends to the end of any *.NDX files remaining.  I presume
the TinyPoint script deletes the NDX files.  I would also presume
that if you modify the batch files that you also kept this logic
in place, or suffer the consequences?

I had a look, and that's what it looks like to me, failure to delete
the NDX files.  Don't ask me why PKT2QWK appends to the NDX files,
that's what PVERT did.  BFN.  Paul.
