Why don't the types work on CDs or Windows discs?

This happens when all the files are shown using the http://rox.sourceforge.net/Icons/application_x-executable.png icon (or similar).

These types of file system can force all files to be marked as executable, which overrides the type system. Either re-configure the file system (if you know how!) or use the option Types=>Ignore eXecutable bit for known extensions.

This option was removed in ROX-Filer 2.3, which should be better at getting the type right without messing around.

If the file has been copied from a CD or Windows disc it will still be executable. Use either the Permissions, Info or Properties menu items to remove the executable permissions.
