It's different from the native system, and I am for consistency in Java approach. If we decided, we show the size as #.# where there's always a digit after the decimal point, I'd rather see it always displayed. It would be easier to scan the sizes.

As of now files having size >0 and <1000 bytes are shown as 1.0 KB.
