I think we should follow the current format for the time being and show the file size similar to how its shown in native tools.

In Windows Explorer, 0 bytes are shown as 0 KB, 1 byte is 1 KB and so on… However, JFileChooser shows these as 0 bytes and 1 bytes in both Java/Metal and Windows L&Fs.

On macOS, Finder shows the size as "Zero bytes" and "1 byte" correspondingly. JFileChooser in Aqua L&F doesn't show the size.
