Working with the Flash File System
In addition, the Secure Copy Protocol (SCP) provides a secure and authenticated method for copying
switch configurations or switch image files. SCP relies on Secure Shell (SSH), an application and a
protocol that provides a secure replacement for the Berkeley r-tools. See the
“Configuring the Switch for
Secure Copy Protocol” section on page 7-41.
Note For more information on how to configure and verify SCP, see the “Secure Copy Protocol” chapter of
the Cisco IOS New Features, Cisco IOS Release 12.2, at this URL:

Local writable file systems include flash:.
Some invalid combinations of source and destination exist. Specifically, you cannot copy these
combinations:
• From a running configuration to a running configuration
• From a startup configuration to a startup configuration
• From a device to the same device (for example, the copy flash: flash: command is invalid)
For specific examples of using the copy command with configuration files, see the “Working with
Configuration Files” section on page B-8.
To copy software images either by downloading a new version or by uploading the existing one, use the
archive download-sw or the archive upload-sw privileged EXEC command. For more information, see
the
“Working with Software Images” section on page B-23.
Deleting Files
When you no longer need a file on a flash memory device, you can permanently delete it. To delete a file
or directory from a specified flash device, use the delete [/force] [/recursive] [filesystem:]/file-url
privileged EXEC command.
Use the /recursive keyword for deleting a directory and all subdirectories and the files contained in it.
Use the /force keyword to suppress the prompting that confirms a deletion of each file in the directory.
You are prompted only once at the beginning of this deletion process. Use the /force and /recursive
keywords for deleting old software images that were installed by using the archive download-sw
command but are no longer needed.
If you omit the filesystem: option, the switch uses the default device specified by the cd command. For
file-url, you specify the path (directory) and the name of the file to be deleted.
When you attempt to delete any files, the system prompts you to confirm the deletion.
Caution When files are deleted, their contents cannot be recovered.
This example shows how to delete the file myconfig from the default flash memory device:
Switch# delete myconfig
