Thanks Bob, Vince & Andrew, all very helpful suggestions.

Well spotted, Vince, it's ParaVision. Thanks for the info regarding
filenames. Makes sense now that I look back on it!

The symbolic link idea is good. How cross-platform compatible is it?
Our archive is linux, but our users use macs & windows boxes.
I think Andrew's idea of using File_Search (and then a combobox, I
guess) looks very promising though, so that's my first port of call.

Thanks,
Chris
