Re: This is a standard numerical analysis issue
To be honest if your developer has set up a system to do this sort of work and then made it so it's dependent on *file names* as any form of control - might I venture to suggest that a cattle prod, some quicklime, a spade and some soft ground is a good idea.
I can think of at least one situation where an OS could happily banjax file names in less than a millisecond - that wonderful way long filenames in Windows of various versions could be royally buggered up if you happened to try editing them in a DOS box (one of several reasons I suspect why most windows systems files are still in the 8.3 format.
It's still risible coding and design - just for a different reason.
