Appendix B Working with the IOS File System, Configuration Files, and Software Images
Working with the Flash File System
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 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-19.
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.
If you attempt to delete the file specified by the CONFIG_FILE or BOOT environment variable, the
system prompts you to confirm the deletion. If you attempt to delete the last valid system image specified
in the BOOT environment variable, 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
