You'll be able to find RAW files in Launcher\BDO\RAW (e.g. Launcher\BDO\RAW\JP for JP client).
If you can't find what you need in the RAW section, then you'll need to add whatever else you want manually in External FEX.
If you have corrupted BDO registry entries or you've moved your game folder this program might not work out of the box, you'll need to select a valid path to your BDO client folder in BDO Patcher => Preferences => BDO Patcher settings. Examples (note that some of the examples have changed due to the publisher change):
For KR that's - ...\Daum Games\Black Desert
For JP that's - ...\GameOn\BlackDesert_live
For EU/NA that's - ...\Black Desert Online
For RU that's - ...\BlackDesert\live
For TW that's - ...\Pearlabyss\BlackDesert
