SharpZipLib fails to extract zipped files with no file extension.

I have a zip file, let's call it "zipfile.zip"

in "zipfile.zip" there is a file with no file extension, let's call it "myfile"

When i run my vb.net code it doesn't extract anything.

When I add a new file call "myfile2.txt" it only extracts that one file, instead of both files.

is this a limitation to the ultility or am I not doing something correctly?

I also tried using the getentry and findentry, both failed to find the file in the zip file.

However I am able to open winzip and extract the file fine.

Please Help.

Here's my very simple code in vb.net

 Dim x As New FastZip, FileFilter As String = Nothing

                Try

                    x.ExtractZip(ZipFilePath, outpath, FileFilter)

                    Return True

                Catch ex As Exception

                    MessageBox.Show(ex.Message, "Unzip file failed", MessageBoxButtons.OK, MessageBoxIcon.Error)

                    Return False

                End Try
