18.432+614,400=

It not working with main i was upload for you, if you can, please dowload main i was upload and test

and :
- 18gb real is 18.432 => i get it
- 600x1024=614,400 => what the 600x1024 ? i don't know
- 18.432+614,400 = put this size on #define AppSize ??

just remove the round to get the decimal

Function NumToStr(Float: Extended): String;
Begin
  Result:= Format('%.3n', [Float]); StringChange(Result, ',', '.');
  while ((Result[Length(Result)] = '0') or (Result[Length(Result)] = '.')) and (Pos('.', Result) > 0) do
  SetLength(Result, Length(Result));
End;

Function MbOrTb(Byte: Extended): String;
begin
if Byte < 1024 then Result:= NumToStr(Byte) + ' MB' else
  if Byte/1024 < 1024 then Result:= NumToStr((Byte/1024*100)/100) + ' GB' else
     Result:= NumToStr(((Byte/(1024*1024))*100)/100) + ' TB'
end;

18600 mb = 18.164 gb
