What does "mz" mean in a Cisco IOS Filename

Kevin Melton

I know that there is some significant meaning to the files that Have a mz in then. Example would be:c2600-is-mz.122-12a.bin.

What does the mz stand for or signify in this instance?

The "m" means the image runs from RAM.

The "z" means the image is zip compressed.

See this link for full details -
