Deleting Files from Boot Flash Memory

When you delete a file from boot flash memory, the system marks the file as deleted. Deleted files cannot be recovered. The boot flash memory is not released after the image file has been deleted, only the image file is marked as deleted.

Caution When deleting files from memory, be careful not to delete all the system images. You should always retain one known good image as a backup image.

To delete a file, use the delete command. The following example demonstrates how a specified image file is deleted using the delete command.

Router# dir

Directory of bootflash:/

1	-rw-	3153784	<no date>	cat2948g-in-mz.old
2	-rw-	3153932	<no date>	cat2948g-in-mz
