If one has an ISO image with file names (final part of full file name) longer than 64 characters, the file name will be truncated to 63 characters. This happens even on the Uniz/Linux variant with the command line version. One doesn't even need to write the files, a simple list of contents will do. Unpacking a ZIP file (or listing it) does not have these limitations. My searches throught the source haven't yielded any clues.
