Only large HDs/RAID-arrays can be used now for bookkeeping. >How many 6 man files are generated? This is the question for Marc. I think the full set of 6-man pawnless EGTs in yk-format is generated - estimated total time is much less than 1 month for Pentium 3.6 GHz computer. I don't have such computer, and the debugging process was very hard for me. Only thank to Marc's verification test some bugs were found. Yakov
