This may be well known, but it wasn't to me...

I asked our crack support guy today how I could best simulate the environment intended for production as regards database layout/access, etc. I had the path statements in all of the MAINs set per the final requirement, with a 'startup-dir\data\' as the last to permit me to test. But I wanted a way to test the intended configuration before actually going to production.
He hmmmm'ed a second and then said 'you should be able to map any directory on your C: drive to any other drive letter. That should work.'.

It sounded strange to me but I went into Explorer-->Tools-->Map Network Drive, selected a drive letter, clicked the 'Browse' button in its window, went down the tree to get my machine, then my C: drive then highlighted a directory name. Clicked the OK button et voila - a directory on my own C: drive now referable as "X:".

It simply never occurred to me to even try such a thing.
I thought other people might be in the same boat, thus this note.

Cheers
