Does this library use System.IO.Compression.DeflateStream for the DEFLATE algorithm?
No. In earlier versions, it did. But the DeflateStream built-into the .NET Framework BCL exhibits anomalous compression behavior on previously compressed data, like mp3 or jpg files. DotNetZip includes a managed compression library, based on ZLIB. It’s fast, fully DEFLATE compliant, and it compresses better than the built in version! And, the DeflateStream that is included in DotNetZip is available for any application to use, under the same terms as the rest of the DotNetZip library.
