This would work

This would not work. The # sign is a comment marker - it has the same
effect in the config file as REM has in a batch file.

Sort files won't go into your system's pag space

You didn't mention whether you rebooted the system after reconfiguring the
sort space. It's not clear from your remarks, whether your config file had
1a. or 1b. If it was 1a., you didn't change anything.

Also, 10 million bytes is *very* unlikely to be close to large enough sort
space for a 5-way join that outputs 5 million rows.

What ON EARTH are you going to with 5 million output rows on a toy
operating system?
