Tosec is quite comprehensive with most things, the dats can be used with rom managers and your 2000 adf's might be recognised and renamed properly!
There are approx 40,000 files recognised by Tosec for the Amiga (This includes maybe a 100 non-adf's tho!) I also have about 7000 non-recognised adf's and I am sure there are alot more than that
So as you can see.. you ain't touching the iceburg yet :eek
checkout
www.tosec.org for the dats etc and get rommanager, romcentre or clrmamepro to sort them
