[QUOTE=OwaziO;2520038]I think i wasn’t clear enough because i posted when i was in a rush, i meant what is the file extension of Linux and what does it stand for?[/QUOTE]
I suspect that you do not understand what you are asking
Linux operating system disk images are released as standard ISO files.
ISO files are a standardised disk image format that can be understood by every decent burning program.
Some softwares have other disc image formats that can be used if more information than a basic TOC & files, but ISO is best for general disc images.
Games/protected discs cannot be distributed in ISO because ISO does not have the means to incorporate bit density/error information into the file.
