About

This is a readonly GNU xorriso based ISO9660 plugin for Midnight Commander.

Pros compared to the classic ISO9660 plugin (the xorriso part of it):

• it is readonly, you cant mess your iso image with it
• it is fast on images containing lots of subdirs
• symlinks are visible
• the boot catalog file is visible
• dirs have actual modified date shown, not the current date

I PR-ed the essentials of the code to the mc repository and it got merged on May 18, 2024.

Installation

The code is based on the xorriso tool. In Ubuntu the package is named the same.

Notice: Pathes used below are from Ubuntu. It might differ in your distro.

There are two relevant config files:

• global /etc/mc/mc.ext (since 4.8.29: /etc/mc/mc.ext.ini)
• local ~/.config/mc/mc.ext (since 4.8.29: ~/.config/mc/mc.ext.ini).

The global config is not loaded if the local one exists.

Local

• put the script under ~/.local/share/mc/extfs.d/ and make sure it is executable
• in mc menu select Command, then Edit extension file
• search for iso9660 and replace Open=%cd %p/iso9660:// with Open=%cd %p/iso9660xl:// there
• save it and exit the editor
• restart mc to apply the changes

Global

• put the script under /usr/lib/mc/extfs.d/ and make sure it is executable
• open /etc/mc/mc.ext (since 4.8.29: /etc/mc/mc.ext.ini) in some editor
• search for iso9660 and replace Open=%cd %p/iso9660:// with Open=%cd %p/iso9660xl:// there
• save it and exit the editor
• restart mc to apply the changes
