> Now you always call `updateMessageFormatPattern` with 1 as the second parameter. Maybe you could initialise both MessageFormat and NumberFormat once and then just use the objects. Or switch back to `MessageFormat.format` method.

MessageFormat.format method was truncating "0" from values like "0.0", "1.0" and so on.
Due to that I initialize MessageFormat and NumberFormat instance.

The first parameter in updateMessageFormatPattern  method changes based on file size, so calling it multiple times to update the pattern.
The second parameter can be removed.
