Hi Axel, I think the problem is the period in your path (after St): F:\Modelle\St. XYZ123\MOI\

Periods in file names are used to separate the name from the file extension, like filename.3dm - having one in the middle of the path will cause various file parsing mechanisms to get confused. With F:\Modelle\St. XYZ123\MOI\ it's going to think that the folder is at "F:\Modelle\" , the filename is "St" and the file extension is " XYZ123\MOI\" .

If you remove the period from the folder name it should probably solve the problem.
