> Key: IO-600
> URL: https://issues.apache.org/jira/browse/IO-600
> Project: Commons IO
> Issue Type: Bug
> Affects Versions: 2.6
> Reporter: Patrick Bender
> Priority: Major
>
> On most unix filesystems only null byte and / are reserved characters. So its
> perfectly valid to have a file called "C:".
> If the getPrefixLength method is called for the path of such a file then it
> returns 2 whereas the expected value is 0.
