Returns an enumerable collection of file and directory items for the directory.

@param prefix
A string containing the file or directory name prefix.
@param options
A {@link FileRequestOptions} object that specifies any additional options for the request. Specifying
<code>null</code> will use the default request options from the associated service client (
{@link CloudFileClient}).
@param opContext
An {@link OperationContext} object that represents the context for the current operation. This object
is used to track requests to the storage service, and to provide additional runtime information about
the operation.

@return An enumerable collection of {@link ListFileItem} objects that represent the file and directory items in
this directory.

@throws StorageException
If a storage service error occurred.
@throws URISyntaxException
If the resource URI is invalid.
