Delete Files from Compact Flash Memory
To delete a file from Compact Flash memory, use the delete flash: 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 enter 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.
Note The dir command does not show deleted files; the show command shows all files, including any
deleted files if the squeeze command has not been entered.
