    "Html": "\r\nHold on now, when you call zip.Save(\"c:\\zipme\\\") , you are passing in a directory name, yes? <br /><br />That is incorrect usage. I guess the Save(string) method should check.  But you must specify a filename, not a directory name, when calling that Save() method.  Try that ?<br /><br />Or maybe you are specifying a real filename.  I don't know for sure.  When I tried this, it worked for me. <br /><br />If you think you are using it correctly, can you send me a short test case?  It should be about 30 lines of code.  I just added some unit tests to the DotNetZip solution (not yet released here), and in the test that covers an empty root directory, it just works.<br /><br /><pre style=\"background-color:#ECECEC; border:dashed .1em #3E62A6; font-family:Consolas, Courier New, Courier, Monospace; font-size:1em; margin-top:0; padding:.5em; height:auto; overflow:auto; overflow-x:auto; overflow-y:auto;\">\r\n        [TestMethod]\r\n        public void ZipDirectoryWithEmptyRoot()\r\n        {\r\n            int i, j;\r\n            int entries = 0;\r\n \r\n            string currentDir = System.IO.Directory.GetCurrentDirectory();\r\n \r\n            string TopLevelDir = GenerateUniqueFilename(\"tmp\");\r\n            System.IO.Directory.CreateDirectory(TopLevelDir);\r\n            _FilesToRemove.Add(TopLevelDir);\r\n \r\n            int subdirCount = _rnd.Next(2) + 2;\r\n            for (i = 0; i &lt; subdirCount; i++)\r\n            {\r\n                string Subdir = GenerateUniqueFilename(\"tmp\", TopLevelDir);\r\n                System.IO.Directory.CreateDirectory(Subdir);\r\n \r\n                int fileCount = _rnd.Next(2) + 2;\r\n                for (j = 0; j &lt; fileCount; j++)\r\n                {\r\n                    CreateUniqueFile(\"bin\", Subdir, _rnd.Next(10000) + 5000);\r\n                    entries++; \r\n                }\r\n            }\r\n \r\n            string ZipFileToCreate = GenerateUniqueFilename(\"zip\");\r\n            _FilesToRemove.Add(ZipFileToCreate);\r\n \r\n            Assert.IsFalse(System.IO.File.Exists(ZipFileToCreate), \"The temporary zip file '{0}' already exists.\", ZipFileToCreate);\r\n \r\n            System.IO.Directory.SetCurrentDirectory(System.IO.Path.GetDirectoryName(TopLevelDir));\r\n            string RelativeDir = System.IO.Path.GetFileName(TopLevelDir);\r\n \r\n            using (ZipFile zip = new ZipFile(ZipFileToCreate))\r\n            {\r\n                zip.AddDirectory(RelativeDir);\r\n                zip.Save();\r\n            }\r\n            System.IO.Directory.SetCurrentDirectory(currentDir);\r\n \r\n \r\n            Assert.IsTrue(CheckZip(ZipFileToCreate, entries),\r\n                    \"Zip file created seems to be invalid.\");\r\n \r\n        }\r\n</pre>",
