I think it is possible, but I would not use such solution. First, as you said - open/skip is buggy for 3 years at least and I really don't understand RT not fixing the problem. Second - once there are index files involved, memo files etc., shared db access, things start to complicate and I would warn from trying to change some data in database that raw way :-) For some basic data extraction simple parser aproach should work, but - I use 50MB databases, almost two hunderds of collumns, relations, etc. :-) Command + /ODBC is good value here, really ... -pekr-
