PurposeCommand or Action
Device# delete usbflash0:myconfig
On Class A and B Flash file
systems, when you delete a
specific file in flash memory, the
system marks the file as deleted,
allowing you to later recover a
deleted file using the undelete
EXEC command. Erased files
cannot be recovered. To
permanently erase the
configuration file, use the squeeze
EXEC command. On Class C
Flash file systems, you cannot
recover a file that has been
deleted. If you attempt to erase or
delete the configuration file
specified by the CONFIG_FILE
environment variable, the system
prompts you to confirm the
deletion.
