Destination file name. For a copy to Flash: File name must be of the form {device>:][<partition>:]<file> where <device> is a value obtained from FlashDeviceName, <partition> is obtained from FlashPartitionName and <file> is any character string that does not have embedded colon characters. A management station could derive its own partition name as per the description for the ciscoFlashPartitionName object. If <device> is not specified, the default Flash device will be assumed. If <partition> is not specified, the default partition will be assumed. If a device is not partitioned into 2 or more partitions, this value may be left out. If <file> is not specified, it will default to <file> specified in ciscoFlashCopySourceName. For a copy from Flash via tftp or rcp, the file name will be as per the file naming conventions and destination sub-directory on the server. If not specified, <file> from the source file name will be used. For a copy from Flash via lex, this string will consist of numeric characters specifying the interface on the lex box that will receive the source flash image.
