Heres an excerpt....
Permanently Delete Files on a Flash Device
When a Flash memory device is full, you may need to rearrange the files so
that the space used by the "deleted" files can be reclaimed. To determine
whether a Flash memory device is full, use the dir command.
To permanently delete files on a Flash memory device, complete the following
task from privileged EXEC mode: Command Purpose
squeeze filesystem:
Permanently delete all files marked "deleted" in Flash memory.
Command : squeeze filesystem
Purpose : Permanently delete all files marked "deleted" in
Flash memory
When you issue the squeeze command, the router copies all valid files to the
beginning of Flash memory and erases all files marked "deleted." At this
point, you cannot recover "deleted" files, and you can now write to the
reclaimed Flash memory space.
----------------------------------------------------------------------------
----
Note The squeeze operation can take as long as several minutes because it
can involve erasing and rewriting almost an entire Flash memory space.
----------------------------------------------------------------------------

Verify Flash
To recompute and verify the checksum of a file in Flash memory on a Class A
Flash file system, use the verify command.
