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.

    Well, it isn't the problem I thought it was. It seems that the Joliet file name structure has a 64 character limit. Thankfully the mastering software (genisoimage, on Linux) as an option to allow longer file names, and nicely 7zip allows these to function properly. I just wnet through a simple test and all is well with the world.

    A note in the documentation might be advisable though. Great program in any event.
