It's all a matter of personal taste I already got used to it and the overhead is negligible.

Thank you. Your solution works with all of the non-spanning zip files I've got on hand for testing. I'll look into this some more One thing you can do to make it a bit faster is to read directly from the decompression stream SourceStream in my example instead of copying it to a memory stream. AFAIR the decompression stream buffers internally and is bidirectional so you should be able to treat it as a memory stream. Yep, that was exactly my idea when I made the shots about.
