Formatting the Compact Flash Memory Cards
This appendix describes how to format the compact flash memory into a Class B flash file system, known as the low-end file system (LEFS), or into a Class C flash file system, which is similar to the standard DOS file system. It also describes how to perform file and directory operations in each file system.
This appendix presents the following major topics:
•
Formatting Procedures for Compact Flash Memory Cards
•File and Directory Operations
Formatting Procedures for Compact Flash Memory Cards
The following sections describe formatting procedures for internal and external compact flash memory cards.
Formatting Procedures
We recommend that you erase (Class B) or format (Class C) new compact flash memory cards to initialize them with either a Class B or Class C flash file system. This ensures proper formatting and enables the ROM monitor to recognize and boot the flash.
Note A compact flash memory card formatted with the standard DOS file system does not support booting from the ROM monitor.
Determining the File System on a Compact Flash Memory Card
To determine the file system of an external compact flash memory card, enter the show slot0: all command. To determine the file system of an internal compact flash memory card, enter the show flash: all command.
•If geometry and format information is not displayed, the card is formatted with a Class B flash file system.
•If geometry and format information is displayed, the card is formatted with a Class C flash file system.
The following examples show sample outputs for Class B and Class C flash file systems:

•Remove the files from a compact flash memory card previously formatted with a Class B flash file system
For external compact flash memory cards, enter the erase slot0: command.
For internal compact flash memory cards, enter the erase flash: command.
The following example shows sample output for formatting an external compact flash memory card with a Class B flash file system:
Router# erase slot0:
Erasing the slot0 filesystem will remove all files! Continue? [confirm]
Current DOS File System flash card in slot0: will be formatted into Low

Formatting Compact Flash Memory as a Class C File System
Use these formatting commands to do the following:
•Format compact flash memory cards with a Class C flash file system
•Remove the files from a compact flash memory card previously formatted with a Class C flash file system
For external compact flash memory cards, enter the format slot0: command.
For internal compact flash memory cards, enter the format flash: command.
The following example shows sample output for formatting an internal compact flash memory card with a Class C flash file system:

Displaying the Contents of a Compact Flash Memory Card
To display the contents (directories and files) of a compact flash memory card formatted with a Class B flash file system, enter the dir {flash: | slot0:} command or the show {flash: | slot0:} command.
The following example shows sample output for displaying the contents of an internal compact flash memory card using the dir flash: command:
Router# dir flash:
Directory of flash:/
1 -rw- 5190020 <no date> cvg224-i-mz

Delete Files from Compact Flash Memory
To delete a file from compact flash memory, enter the delete {flash: | slot0:} command, followed by the squeeze {flash: | slot0:} command.
When a file is deleted in the Class B flash file system, the memory space occupied by the deleted file is not released until you enter the squeeze {flash: | slot0:} command. Although the memory space once occupied by the deleted file remains, the deleted file cannot be recovered. To release the memory space occupied by a deleted file, enter the squeeze {flash: | slot0:} command.
Note The dir {flash: | slot0:} command does not show deleted files; the show {flash: | slot0:} command shows all files, including any deleted files if the squeeze {flash: | slot0:} command has not been entered.
The following example shows sample output for deleting a Cisco IOS file from an external compact flash memory card, and then releasing the memory space originally occupied by the file:
Router# dir slot0:

Remove a Directory
To remove a directory from compact flash memory, use the rmdir {flash: | slot0:} command.
Before you can remove a directory, all files and subdirectories must be removed from the directory.
The following example shows sample output for displaying the contents of an internal compact flash card, then removing the subdirectory named test-config:
Router# dir flash:
Directory of flash:/config/
1581 drw- 0 Mar 01 1993 23:50:08 test-config
128094208 bytes total (121626624 bytes free)
Router# rmdir flash:/config/test-config
Remove directory filename [/config/test-config]?
Delete flash:/config/test-config? [confirm]
Removed dir flash:/config/test-config
Router# dir flash:
Directory of flash:/config/
No files in directory

Enter a Directory and Determine Which Directory You Are In
To enter a directory in compact flash memory, use the cd command.
To determine which directory you are in, use the pwd command.
If you enter only cd, you go to the default home directory, which is flash:/.
The following example shows sample output, respectively, for the following actions:
•Entering the home directory of a compact flash memory card in an internal slot (flash:/)
•Verifying that you are in the home directory
•Displaying the contents of the home directory
•Entering the /config directory
•Verifying that you are in the /config directory
•Entering the home directory of a compact flash memory card in an external slot (slot0:/)
•Verifying that you are in the slot0:/ directory
•Returning to the home directory (flash:/)
•Verifying that you are in the home directory
