Hi onedreamuser.
JUNOSe manages directories automatically. It hides all details about the underlying file system, managing file types automatically. JUNOSe presents the user with a flat file system, even though, internally, it uses directories as necessary.
The only directories exposed are the incoming/ and outgoing/ directories when the ftp-server is enabled.
As a result, there are no plans for pwd and mkdir commands.
Please let me know if this answers your questions.
Phil
