> It's sometimes useful to extract File System metadata from files that people often see when browsing a file on an operating system.
> Examples:
> * POSIX permissions
> * Datetime stamps, including: lastModified, creationTime, lastAccessTime
> * Is a symbolic file?
> * Is a directory?
> * File owner
> * Is hidden file?
> etc.
> Java 7's Files.getAttributes [1] does this in a platform-generic way. We should leverage this and add an extractor for the benefit of the community.
