Can nero suport the long file name?

I use the nero 6.319 version;
when I send the directory name(for example:\TestDVDWriter\xml) to the application, the long-file-name files bellow this directory can be burn to the dvd;
but when I send the full path name to the application (for example:E:\NFC\Source\TestDVDWriter\xml\2162644125.640.3217197903.49.dcm)
then the filename can not burn to dvd correct!.
I don’t knew why?
