Is it possible to add files to a existing WIM image?

Apr 14, 2013 at 5:53 PM
I am trying to add a folder and files to the windows 8 boot.wim.

var wim = new WimFile(File.Open(targetFile,FileMode.Open));
var wimFileSystem = wim.GetImage(wim.BootImage-1)

But I get an Exeption "System.NotSupportedException: Operation is not supported.".
Is there any way of edit a wim file?
