3 days, one zip archieve, 5 files

Spent almost 3 days on figuring out what is wrong with my fully, superficially, dynamically, amazingly in-memory created, fabulous zip archieve, which uses icsharpcode ...

Review, test, change test, add , test, remove, test, duplicate, test, tweak, test, swirl, test...

Result : nothing...

winzip and winrar opens it... but windows compressed folder seems to hate it somehow.
