"The given path's format is not supported" error raised

Jun 6, 2012 at 7:07 AM

When the contents of a zip file contain an underscore "_" i am receiving this error. I have replicated the error using the supplied example code for DotNetZip Tool v1.9.1.900

Any idea as to the cause? 7Zip will extract and created the necessary directories and files that contain underscores. 

any advise would be appreciated, even a line of code that this errors on in the source so i can see for my self what is happening.

 

Tanks in advance
