Hi .. I'm currently working on a project that will read/open a password protected PKZip file. The zip files can range from 1mb to over 3GB in size. I am writing a code (kind of like a text editor) in VB.net that will let users open the zip file. I tried opening a 1gb text file (not zipped) using Readblock. I'm not sure how to do the same with a zipped file without extracting the file. Is it possible to read a zip file without extracting it? Any help will be appreciated. Thanks!

Solution 1

This project offers wrapper classes for SharpZipLib and DotNetZip, as well as an example project and instructions on how to use it all. Using either free library and it's wrapper class would make this easy.
