Recently I had to build a private online photo album application. I planned to provide the users the option to upload images as a ZIP file. I needed this option to be implemented in ASP.NET 1.1, as my hosting service provider didn't have .NET 2.0 support. Online search lead me to a blog with this wonderful idea of using the ZIP option in J# and it really attracted me. I did want to try it out and the results were pretty cool. Even though this sample application has been written in .NET 1.0, .NET Framework 2.0 has libraries to work with compressing and uncompressing of files. I will soon come up with an article to illustrate the use of .NET 2.0 libraries for compress and uncompressing functionalities. In this article, I will explain the usage of ZIP functionality in J# from C# code. The code in this application has been designed to reuse in a copy paste fashion and not as a library.
