Working with the Flash File System
Deleting Files
When you no longer need a file on a flash memory device, you can pe rmanently 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 usin g 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
Creating, Displaying, and Extracting tar Files
You can create a tar file and write files into it, list the files in a tar file, and extract the files from a tar
file as described in the next sections.

Creating a tar File

To create a tar file and write files into it, use the privileged EXEC command:
archive tar /create destination-url flash:/file-url
For destination-url, specify the destination URL alias for the local or network file system and the name
of the tar file to create. These options are supported:
•For the local flash file system, the syntax is
flash:
•For the FTP, the syntax is ftp:[[//username[:password]@location]/directory]/tar-filename.tar
•For the RCP, the syntax is rcp:[[//username@location]/directory]/tar-filename.tar
•For the TFTP, the syntax is tftp:[[//location]/directory]/tar-filename.tar
The tar-filename.tar is the tar file to be created.
For flash:/file-url, specify the location on the local flash file system from which the new tar file is
created. You can also specify an optional list of files or directories within the source directory to write
to the new tar file. If none are specified, all files and directories at this level are written to the newly
created tar file.
