@rickysaltzer - I'm a bit confused by this default value... is the default
to filter files starting with "."? Does this change this processor's behavior?

> There are times where you may want to only extract a portion of an archive,
> such as a specific folder, or perhaps a specific file. Similar to how the
> {{GetFile}} processor works, we should provide a property ({{File Filter}})
> which by default extracts all files. The user can modify this property to
> extract only files they wish to process downstream.
