  TransferManager tm = new TransferManager(myCredentials);

    ObjectMetadataProvider metadataProvider = new ObjectMetadataProvider() {
        void provideObjectMetadata(File file, ObjectMetadata metadata) {
            // If this file is a JPEG, then parse some additional info
            // from the EXIF metadata to store in the object metadata
            if (isJPEG(file)) {
                metadata.addUserMetadata("original-image-date", 
                                         parseExifImageDate(file));
            }
        }
    }

    MultipleFileUpload upload = tm.uploadFileList(
            myBucket, myKeyPrefix, rootDirectory, fileList, metadataProvider);
