Max number of files on root of a dvd


I’m trying to burn a DVD with 95,000 files (tiff images) to the root of the DVD. The size of the dvd is only 3.5gb. Nero allways fails when trying to burn the dvd.

Is there a limit to the number of files that can be put on the root of the dvd?

I need the files on the root. Is there any other software that may deal with burning this amount of files to the root?
