+When compressing, do not save the original file name and time stamp.
+This information is saved by default when the deflate scheme is used.
+When uncompressing, do not restore the original file name and time stamp.
+By default, the uncompressed file inherits the time stamp of the
+compressed version and the uncompressed file name is generated by
+stripping the

+extension from the compressed file name.

+When compressing, save the original file name and time stamp in the
