why is 5.7MB funny with 6000000 bytes ?   or are you talking about
something else?  Don't forget that BYTES and thus MEGABYTES are found by
powers of 2.  They do not function like the decimal "bits".  quick way to
do the conversion is divide bytes by 1024 to get Kilobytes and then again
by 1024 to get Megabytes.  This is how it should be displayed.   Or am i
missing the point of your comment?
