---------------------------------------

Added testcase in r1686461 that shows IO-423 fixed this too

>                 Key: IO-466
>                 URL: https://issues.apache.org/jira/browse/IO-466
>             Project: Commons IO
>          Issue Type: Bug
>          Components: Utilities
>    Affects Versions: 2.4
>            Reporter: Ray Navarette

> Consider the following:
> {code:java}
> File fooDir = new File("/temp/foo");
> File fooFile = new File("/temp/foo.txt");
> FileUtils.directoryContains(fooDir, fooFile); // returns true, should return false
> {code}
> fooFile is a sibling of fooDir.  fooDir does not contain fooFile.
> This is due to the way FilenameUtils.directoryContains is implemented in that this method uses a simple 'startsWith' comparison.  A related bug is filed for the FilenameUtils method that I believe should be fixed as well.
