Tyler Barrus commented on IO-416:
---------------------------------

Perhaps something like incrementing the file name to the first non-collision 
name would suffice. Something like:
{code}
// input: /directory/test.txt is a file that exists
File f = incrementFileName(new File("/directory/test.txt"));
try {
        FileUtils.touch(f);
} catch (IOException e) {
        e.printStackTrace();
}

// output: a new file at /directory/test (1).txt
{code}

I have code to do this but need to work to get it in patch form. Once it is in 
a patch, I can post it here.

> 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}
