In DW6 a few things are different. On Windows DataWarrior.exe does not contain the main code anymore. It just contains a small launcher that may download an update and then launches the newest datawarrior.....jar. You can launch the same jar from the command line with e.g.:

"C:\Program Files\DataWarrior\jre\bin\java" -Xmx16g -Xms8g --add-exports java.base/jdk.internal.module=ALL-UNNAMED -jar C:\ProgramData\DataWarrior\datawarrior_v06.02.01.jar

As before, you can change Xmx (max memory) and Xms (memory at start) to your needs. You could also change these settings in the DataWarrior.exe using a hex editor, but that would be a kind of a hack...
