I may be missing something, but the program doesn't seem to recognise filenames beginning with 00 (double zero)
Edit: Please ignore. This is a symptom of a deeper problem I have since a recent reinstall with Windows in general only partially recognising some files - some apps see them, some don't.
Edit 2: I have now found the problem, and I probably wouldn't have done if I hadn't posted here. Somehow the files in question were marked as Hidden during the reinstall.
