[Dx4win] splitting up my log

[Courtney Judd K4WI]

Hey all, looking for some help here with dividing my log up into two or more 
parts. I have version 7.02.15 with 104K qso's entered. My problem is that 
sending this log as is to LOTW gets rejected by the ARRL server as too big.. 
11 meg... I have read the manual and help files and still have not figured 
out how to do this... very confusing to say the least! Any help would be 
appreciated... thanks and 73's Cort K4WI
