PdfEditor.Concaternate OutOfMemoryException


we are using the Method PdfFileEdtor.Concaternate(string[] files, string outFile).

We have very big (450 MB) PDF files and therefore an UNHANDLED OutOfMemory Exception will be thrown, but not to the outside. If i surround the call with try…catch, the catch block will never be reached. I set AllowConcatenateExceptions to true, but it still not throwing the exceptions outside.

How can we handle those Exceptions if they will not be thrown correctly??

Kind Regards,
