The squeeze command permanently removes deleted files from flash memory and 
makes all other (undeleted) files contiguous to conserve storage space.

To permanently remove deleted files from a flash memory directory, but leave the 
other files intact, enter the squeeze device-name command.

Where device-name can be slot0:, slot1:, or bootflash:.

Milo# squeeze slot0:

All deleted files will be removed, Continue? [confirm]y

Squeeze operation may take a while, Continue? [confirm]y

In this example the character:

e in the last line indicates that the flash memory area is erased. This erase 
operation must be accomplished before any write operation to the flash 
memory area can begin. 

b indicates that the data about to be written to the flash memory area has been 
temporarily copied. 

E indicates that the sector temporarily occupied by the data is erased.

S indicates that the data is written to its permanent location in flash memory.

Z indicates that the log is erased following the successful squeeze operation.

To prevent loss of data from a sudden power loss, the “squeezed” data is 
temporarily saved to another flash memory area reserved specifically for system 
use.

During a squeeze operation, the system maintains a log of executed squeeze 
functions, so that the system can return to the proper place and continue the 
operation in the event of a power failure.
