interface nsIFile;
* This interface provides a means for enumerating the contents of a directory.
* It is similar to nsISimpleEnumerator except the retrieved entries are QI'ed
* to nsIFile, and there is a mechanism for closing the directory when the
* enumeration is complete.

* Retrieves the next file in the sequence. The "nextFile" element is the
* first element upon the first call. This attribute is null if there is no
* next element.
readonly attribute nsIFile nextFile;
* Closes the directory being enumerated, releasing the system resource.
* @throws NS_OK if the call succeeded and the directory was closed.
* NS_ERROR_FAILURE if the directory close failed.
* It is safe to call this function many times.
