• To view extended information about a specific file, enter the following command:
hostname# show file information [path:/]filename
The default path is the root directory of the internal flash memory (disk0:/).
For example:
hostname# show file information cdisk.bin
disk0:/cdisk.bin:
type is image (XXX) []
file size is 4976640 bytes version 7.0(1)
The file size listed is for example only.
Deleting Files from Flash Memory
You can remove files from flash memory that you no longer need. To delete a file from flash memory,
enter the following command:
hostname# delete disk0: filename
By default, the file is deleted from the current working directory if you do not specify a path. You may
use wildcards when deleting files. You are prompted with the filename to delete, and then you must
confirm the deletion.
Erasing the Flash File System
To erase the flash file system, perform the following steps:
Step 1 Connect to the ASA console port according to the instructions in the “Accessing the
ASA Services Module Command-Line Interface” section on page 1-2 or the “Accessing the Appliance
Command-Line Interface” section on page 1-1.
Step 2 Power off the ASA, then power it on.
Step 3 During startup, press the Escape key when you are prompted to enter ROMMON mode.
Step 4 Enter the erase command, which overwrites all files and erases the file system, including hidden system
files.
rommon #1> erase [disk0: | disk1: | flash:]
