Sebb commented on IO-416:
-------------------------
bq. Also, is there a util that lets us know what the max file name length is
for a file? If there is, it would be trivial to add the check in to make sure
it isn't too long.
I don't think so. It is OS-specific. There is usually a limit on pathname
segments as well as total pathname length.
But I don't see any point in checking the length.
There are other reasons why file creation may fail later; the application needs
to handle these anyway.

> Create a FileNameUtil or FileUtil facility that allows for creating a one-up
> extension on files that already exist.
> example:
> archive
> +-- file.txt
> +-- file.txt.1
> +-- file.txt.2
> {code}
> File file = FileNameUtils.nextOneUpFile("/archive/file.txt");
> System.out.println(file)
> // output: /archive/file.txt.3
> {code}
