Deleting Files from the Flash Memory
To delete a file from the flash memory, use the delete: filename command followed by the squeeze flash:
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 use the squeeze 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: command
The following is sample output for deleting a Cisco IOS file from the flash memory, and releasing the
memory space originally occupied by the file.
