You are responsible for file management. Table 32 shows the types of system files and their corresponding extensions.
Table 32: Types of System Files and Corresponding Extensions
System files may reside in four locations:
The system space contains files for system operation. For example, the current software configuration is stored in the system space.
The user space is reserved for FTP server operations and has the typical directory structure of a secure FTP server. The root or top level directory is a read-only directory that contains two subdirectories:
Users can transfer files through FTP to the user space from a network host and vice versa. However, users cannot access the system space through FTP. To install a file from the user space to the system space, use the copy command. For detailed information about transferring files between locations, see Transferring Files.
To conserve NVS and minimize the installation time, files are not stored in both the system space and the user space. When you issue the copy command to install a file from user space to system space, the E-series router establishes a link to the file, but does not make a physical copy.
