It might have been a coincidence I didn't see that before. How can I assure that a filter to "*.crp", would only retrieve those files and not files with a name such as "MyFile.crp2"?

You can use a Linq query instead which is much more intuitive:

Dim loDirectory As New DirectoryInfo(cDirectory)

for Each loFile in loDirectory.GetFiles().Where( Function(f)  f.Extension.ToLower() = ".crp" )
...
Next
