Duplicated files & directories appear when it appends by CompressDirectory method.

For example: var arcFullName = @"C:\blablabla.7z"; var dirFullName = @"C:\Tmp\ForPacking"; //include file "test.txt" var cmpr = new SevenZipCompressor(); cmpr.CompressionMode = File.Exists(arcFullName) ? CompressionMode.Append : CompressionMode.Create; cmpr.PreserveDirectoryRoot = true; cmpr.CompressDirectory(dirFullName, arcFullName); 1st run -> create archieve file "c:\blablabla.7z" with "ForPacking\test.txt" 2nd run -> archieve file "c:\blablabla.7z" consist of directory "ForPacking" with two files "test.txt" !? What's wrong?
