Extracting from Actual Client 8.1.0.28833

Hello i try to Setup a Trinity Server . with the actual Master Branch or 3.3.5.

My Problem is the Extration of the wow Files from an actual wow-Client 8.1.0.28833 . The Extration doesnt find the files to extract.

It doesnt matter were i put the Extration Files . Its a German Client.

Is it actualy possible to extract from this Client or where do i get the files for the privat Server ?

Thanks and a happy new year.
