4000 Router Series Fundamentals Configuration Guide

Managing the file system

This chapter describes how to manage the device's file system, including the storage media, directories,

and files.

IMPORTANT:

• Before managing storage media, files, and directories, make sure you know the possible impacts.

• A file or directory whose name starts with a period (.) is considered a hidden file or directory. Do not

give a common file or directory a name that starts with a period.

• Some system files and directories are hidden.

The following matrix shows the storage medium and router compatibility:

Storage medium naming rules

If a storage medium is the only storage medium of its type on the device, it is named by its type. For

example, if the device has only one Flash, the name of the Flash is flash. If the device has only one CF

card, the name of the CF card is cfa0.

File name formats

IMPORTANT:

Enter a storage medium name in lower case, including the slot number string (if any). Otherwise, the

following error message is displayed: "The file or directory doesn't exist." Folder names and file names

are case insensitive.

When you specify a file, enter the file name in one of the formats shown in Table 11, and Table 12. When

you specify a directory, follow the rules for the drive and path arguments.
