title: Is there a library to unzip .Z files using VB.NET?
body: <p>I need to unzip a list of .Z files which will be kept in a folder using Visual Basic.NET.
  For example, consider that there is a folder like <code>C:\FilesToBeUnzipped</code>. Inside this folder there will some 5 to 6 files with .Z as extension. I need to unzip all these .Z files and save the unzipped files in a folder like <code>C:\UnzippedDataFiles</code>. </p>
  
  <p>Is this possible in VB.NET? Is there any free component or class library to achive it? </p>
