well i don't have time to test but there should be a option to use compressed sets where it would create something like:
z:\Commodore Amiga - Games - [ADF] (TOSEC-v2006-10-19_CM).dat\4D Sports Boxing v1.0 (1991)(Mindscape)(Disk 1 of 2)[cr CSL].zip
...and inside the zip there would be the rom "4D Sports Boxing v1.0 (1991)(Mindscape)(Disk 1 of 2)[cr CSL].adf"
other idea for damien to reduce the path lenght could be not using the dat version / using the tosec folder structure, so instead of:
z:\Commodore Amiga - Games - [ADF] (TOSEC-v2006-10-19_CM).dat\
if could be:
z:\Commodore\Amiga\Games\[ADF]\
anyway good luck with it and try using compressed sets or something like that to rebuild to zipfiles
