6.1 File System Overview

The router effectively manages all files by means of the file system.

6.1.1 File System

The file system manages the files and directories in the storage devices. It can create, delete,
modify, and rename a file or directory and display the contents of the file.
The file system has two functions: managing the storage devices and managing the files that are
stored in those storage devices.
Performing File Operations by Means of the File System
After logging in to the router by using the console port, Telnet, or STelnet, you can manage
storage devices, directories, and files.

6.1.2 Methods of File Management

You can manage files by means of the file system, FTP or SFTP.
Performing File Operations by Means of FTP
You can configure the router as the FTP server, and log in to the router from the user terminal
to transmit files and manage directories on the FTP server.
Performing File Operations by Means of SFTP
SSH supports Secure File Transfer Protocol (SFTP), which enables users to remotely and
securely log in to the router to manage files. SSH guarantees secure data transmission on a
conventional insecure network by authenticating the client and encrypting data in both
directions.
