A merger of Mega2006+TWIC+some other commented is about 560MB for the DB, 160MB index.

The main drawback of scid actually is its lack of inicees ;) This is IMHO the main point where CB is just plain better, especially as it allows for userdefined indicees as far as I know it. > > We can already easily import one DB into another > > with Scid, (CTRL D + drag and drop).

This only works if I do not sort the DB, but actually your fast tree mode requires sorting the DB as it does not work on a properly sorted index. > Or : I set a PGN tag, (v12) that I remove after diff's > generation That is what I suggested except that I did not want to remove it. -- Kind regards, / War is Peace. | Freedom is Slavery.
