Project Description
The Microsoft .NET Framework {v2.0 v3.0 v3.5} includes base class libraries supporting compression within streams - both the Deflate and Gzip formats are supported. But the System.IO.Compression namespace provides streaming compression only - useful for communicating between cooperating parties but not directly useful for creating compressed archives, like .zip files. The built-in compression library does not know how to format zip archive headers and so on.
To address this, this simple class library augments the System.IO.Compression.DeflateStream class, to provide handling for Zip files. Using this library, you can write .NET applications that read and write zip-format files.
Frequently Asked Questions
How does this Zip Library work?
There's a single DLL, a single assembly, fully managed code, written in C#, that provides support for reading and writing Zip archive files.
What do I need to "do" zip files from within my application?
To use the zip capability in your applications, you need to be using the .NET Framework 2.0 or later. You can use the Zip library from any application, whether a console application, a Windows-Forms application, a server-based application, or something else.
How big is the library?
The zip DLL is about 36k in size. There is no other pre-requisite.
Limitations
--------------------------------
There are numerous limitations to this library:
it does NOT support encryption, file comments, or double-byte chars in filenames.
it does NOT support file lengths greater than 0xffffffff.
it does NOT support "multi-disk archives."
it does NOT do varying compression levels.
it can actually expand the size of previously compressed data, such as JPG files.
there is no GUI tool

The readme you've posted here is quite old. The zip DLL is about 400k in size. It handles unicode, it handles large files, it does varying compression levels, and it does not expand previously compressed data. Get the latest version: v1.8.
