That's exactly my point.

I also asked for the summary. That time it was a bit different:

To keep file size similar to native file system, JFileChooser displays file sizes with one decimal point precision.

The original issue is that we displayed a zero-sized file as 1 KB. It's stated in the bug subject and in the bug description with more details.

The initial fix was to display it as 0 bytes, which leads to localisation problems, especially if we take into account 1 byte.

Eventually, it was decided to display the size in KB. Thus zero-sized file is displayed as 0 KB, and one-byte-sized file is displayed as 1 KB. This is fine.

Later on, the decimal point was added to mimic native file navigation app in Ubuntu. Now for files larger than 1 KB, the size is shown up to one decimal point. Yet all the files below 1 KB are still displayed as 1 KB. I think it is confusing. If we care to display the size with one decimal point for larger files, why can't we display the size of smaller files with the same precision?

So, 0 bytes is 0.0 KB; > 0 and <= 100 bytes is 0.1 KB, and so on.

Alternatively, drop the decimal altogether.
