Displaying Contents of the Flash Memory

To display the contents (directories and files) of the flash memory formatted with a Class B flash file system, use the dir: command.

The following is sample output for displaying the contents of the flash memory with a Class B flash file system:

Router# dir

Directory of flash:/

1-rw- 30564420 <no date> ngmwr-advipservicesk9-mz

2-rw- 30564420 <no date> ngmwr-backup

83623932 bytes total (22494964 bytes free)

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.

Router# dir

Directory of flash:/

1-rw- 30564420 <no date> ngmwr-advipservicesk9-mz

2-rw- 30564420 <no date> ngmwr-backup
