Dear all,

I'm currently using Dotnet 4.0 with VS 2010..
I want to test zip file using DotnetZip library.

this following is my coding :
using Ionic.Zip;

namespace testzip
    public partial class Form1 : Form
        public Form1()

        private void button1_Click(object sender, EventArgs e)
            using (ZipFile zip = new ZipFile())
                string inputdirectory = @"D:\BackUp\20130102.bak";
                string outputdirectory = @"D:\BackUp\20130102.ZIP";
                inputdirectory = inputdirectory.Replace("\\", "\\\\");
                outputdirectory = outputdirectory.Replace("\\", "\\\\");
                DirectoryInfo di = new DirectoryInfo(inputdirectory);
                //zip.AddDirectory(inputdirectory, "ZipTest");
                zip.Comment = "This zip file is created using DotNetZip library";

this code is working fine... I can zip my file name 20130102.bak successfully, but when i use Winzip or winrar to extract -> then choose extract here-> it not only extract my file, but also include sub folder name BackUp.
I want to zip and extract without sub folder, Please help me...

This is a setting for winzip, it has nothing to do with your code.

Dear Christian,

Thank for your quick reply...
But i wonder that if i use winzip or winrar to zip other file, for example file name 123.bak .Then i use winzip to extract here it not include sub folder. it give me only this file.
Ex : 1/ my file name is 123.bak--> after zip this with winzip -->file name is
2/ use winzip--> extract here --> 123.back

That why i think it not winzip setting problem.
