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
16777216 bytes total (7315372 bytes free)
Router# delete cat2948g-in-mz.old
Delete filename [cat2948g-in-mz.old]?

Router# dir
Directory of bootflash:/
