There are cwp files, I hope I can read them with SPlat, if not, I saved all my PCs I ever had, so there must be the right Software on one of them, puuuuuh.......
@Adq
Thank you! Over Musicompress with google I came to WaveZIP. This software I have in my archieves, so it must be that!
Thanks a lot, I'll try this one.
