--- Comment #6 from Elvis Angelaccio <elvis.angelac...@kdemail.net> --- I was only able to reproduce the issue with Windows installation's ISOs. It's a problem with UDF file systems within the ISO file, and looks like an upstream limitation: https://github.com/libarchive/libarchive/issues/298 That's also why file-roller shows them as empty. However, you should be able to open "normal" (non-UDF) ISO files. Please try to open the ISO with e.g. Ubuntu or OpenSUSE live CD/DVD. If you can't, please start Ark from terminal, try to open again the ISO and post here the output. Other infos that would be useful: for each ISO file that Ark opens with only README.TXT in it, please post here the output of: $ file --mime-type /path/to/the/ISO -- You are receiving this mail because: You are watching all bug changes.
