what is the point of making directories in a Cisco router. I noticed its was kinda like Linux mkdir and all that stuff, but what is the purpose?

1 Answer 1


Cisco devices have a filesystem, much like other computing devices. I really don't understand your confusion. The file system is used to store boot images an other necessary files.

I noticed its was kinda like Linux mkdir and all that stuff

Did you ever think that Linux was like Cisco IOS, which predates Linux by many years?

  • so, they are there for storing files and other stuff ?

  • Yes. You can have multiple instances of IOS images, there are things like the HTTP pages, etc. Cisco has always had a filesystem for its files.

  • Just a comment on chronology: Linux (first released 1991), is of course developed to be like Unix, which had mkdir and chdir in its first release in 1972. Unix copied the hierarchical filesystem (and many other innovations) from Multics (1969) which had "create directory" as cd and "change working directory" was cwd. Cisco was founded in 1984.

  • @jonathanjo, I was just being kind of a smartass. I knew the chronology. We once had a person assert that IOS was derived from Linux, but Ricky set him straight.

  • @RonMaupin I was just being kind of a historian -- seemed like a good idea to have the dates on this answer for any who didn't know the chronology. Kind regards.
