Unzipping files programmatically

[Ted Osberg]

I was wondering if there was a way to unzip .zip files programmatically in vb.net or vb6 without using winzip (or their command line utility) or another application?. Obviously, there is but I guess Im not sure how to go about doing it. Can anyone point me in the right direction.

It is possible only if you know how WinZip are compressed! It makes sense that you must know what is the Compression Algorithm used in WinZip in order for you to Decompress them!

And worst of all, its not an easy task even to implement the process... Take a look at these article
