The contents of the zipfile is placed in the targetfolder. You can use DirectoryInfo.GetFiles() to process each file in the targetdir and extract them afterwards if you want.

Another option would be to use the FastZip(FastZipEvents) to create the new instance so you get notified of each individual file that is being unpacked. When you unpack another zipfile, you can respond to that on the spot.

Sorry I cannot give you any code. I don't have the lib installed.

Can't v use a loop that iterates within those line of code n the code keeps on unzipping the files ? eg :
for this code:

private void btnok_Click(object sender, EventArgs e)
      {
        FastZip zp = new FastZip();
        zp.ExtractZip(txtpath.Text, txtdestination.Text, "");
        MessageBox.Show("Folder Unzipped Successfully");

                }

can't v use the loop so that this piece of code keeps on repeating n unzipping all zip files...ne idea how to write the loop code?

you can try something like this:

bool isToZip=true
String sourceFileName="file name";
String destinationFile="destination file name";
while(isToZip)
{
      //1.un zip source file to destinaion file, i.e. sourceFileName
      //2. get destination file,i. e. destinationFile
      //3. if destination file is ziped one, sourceFileName=destinationFile
     //4. give new destinationFile
}

i have just given a hint, it should work

              string fname = (txtpath.Text.Substring(txtpath.Text.LastIndexOf("\\") + 1));
              zp.ExtractZip(fname,txtdestination.Text,".Zip");
           }
