===== solution 2 =====

Under Linux, you can create an ISO image from a folder using a command line argument with the mkisofs tools. The following example creates an ISO image suitable to be used under Windows:
  * -J option is used to generate Joliet directory records in addition to regular ISO9660 filenames (useful when the discs are to be used on Windows machines). 
  * When using the -J, it is recommended to add the -R option (Rock Ridge protocol). 
  * Finally, the -l option manages the long names.
<cli prompt='#'>
# mkisofs -J -l -R -V "Label CD" -iso-level 4 -o output.iso input_directory
</cli>
