Working with the Flash File System
Creating and Removing Directories
Beginning in privileged EXEC mode, follow these steps to create and remove a directory:
To delete a directory with all its files and subdirectories, use the
delete /force /recursive
filesystem
:/
file-url
privileged EXEC command.
Use the
/recursive
keyword to delete the named 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.
For
filesystem
, use
flash:
for the system board flash device. For
file-url
, enter the name of the directory
to be deleted. All the files in the directory and the directory are removed.
Caution
When files and directories are deleted, their contents cannot be recovered.
Copying Files
To copy a file from a source to a destination, use the
copy
source-url destination-url
privileged EXEC
command. For the source and destination URLs, you can use
running-config
and
startup-config
keyword shortcuts. For example, the
copy running-config startup-config
command saves the currently
running configuration file to the NVRAM section of flash memory to be used as the configuration during
system initialization.
You can also copy from special file systems (
xmodem:
,
ymodem:
) as the source for the file from a
network machine that uses the Xmodem or Ymodem protocol.
Network file system URLs include
ftp:
,
rcp:
, and
tftp:
and have these syntaxes:
•
FTP—
ftp:
[[
//
username
[
:
password
]
@
location
]
/
directory
]
/
filename
•
RCP—
rcp:
[[
//
username
@
location
]
/
directory
]
/
filename
•
TFTP—
tftp:
[[
//
location
]
/
directory
]
/
filename
Local writable file systems include flash:.
