Displaying the Contents of a Flash Memory Card

To display the contents of a Flash memory card, enter the show {slot0: slot1:} command, for example:

Router# show		slot1:
PCMCIA Slot1 flash directory, partition 1:
File	Length		Name/status
1	1933052		c3640-i-mz.111-6.3.AA
[1933116 bytes			used, 6455492 available, 8388608 total]
8192K	bytes of		processor board PCMCIA Slot1 flash (Read/Write)
PCMCIA Slot1 flash directory, partition 2:
File	Length		Name/status
1	3399444		c3640-j-mz.111-7.AA
[3399508 bytes			used, 794796 available, 4194304 total]
4096K	bytes of		processor board PCMCIA Slot1 flash (Read/Write)
PCMCIA Slot1 flash directory, partition 3:
File	Length		Name/status
1	2359		running-config
[2424	bytes used, 4191880 available, 4194304 total]
4096K	bytes of		processor board PCMCIA Slot1 flash (Read/Write)

Similarly, you can display the contents of system (onboard) Flash memory by entering the show flash: command.

Copying a File from System Flash Memory to a Flash Memory Card

You can use a Flash memory card to store a backup copy of a Cisco IOS image or other file. Follow these steps to copy a file from system (onboard) Flash memory to a Flash memory card:

Step 1 Enter privileged EXEC mode:

Router> enable

Password: <password>

Step 2 Enter the copy flash:[partition:filename] {slot0: slot1:}[partition:filename] command. Replace

partition with the partition number and filename with the name of the file, for example:

Router# copy flash:2:TESTFILE slot0:3:TESTFILE

PCMCIA Slot0 flash directory, partition 3: No files in PCMCIA Slot0 flash

[0 bytes used, 4194304 available, 4194304 total] Verifying checksum for 'TESTFILE' (file # 1)... OK Erase flash device before writing? [confirm] n

Note If you omit the partition and filename variables, you are prompted for them.
