Do not understand your question.Do you want to determine if a qvd exists from the load script, or do you want to do that from a bat file or C# executable?

Why do you need a c# exe to determine whether a qvd exists when reloading your dashboard? Just use the built-in functions:

Let vQVDExists = (Alt(QvdNoOfRecords('E:\QVDFiles\myQVDFile.qvd'), 0) > 0);

If vQVDExists Then

... do stuff

Else

... do other stuff

End If
