    "Description": "Hi All,\n\nI've found the issue wasn't to do with the file naming... It's because the output file (that was to be created) was \non a UNC path share. By creating the output locally, & then using File.Move(..., <unc path>) I got around the error.\n\nRegards\n\nC.\n\n\n--------------------------------\n\nHi Team,\n\nI'm having the error as shown in:\n\n      http://dotnetzip.codeplex.com/discussions/223754\n\nI'm using V1.9.1.8 from A .NET 3.5 application, running on WindowsServer 2003 R2.\n\nI don't think it is a windows problem.  I think it is either a long file name or extension issue.\n\nI am trying to zip a folder created by a 3rd-part app which produces long file name differing by their extension (or 2).  ie: The folder which fails to Zip contains\n\n<a 106 char file name, including spaces>.msg\n<a 106 char file name, including spaces>.msg.xml\n<a 106 char file name, including spaces>.pdf\n<a different 106 char file name, including spaces>.msg\n<a different 106 char file name, including spaces>.msg.xml\n<a different 106 char file name, including spaces>.msg.pdf\n\n\nThe exception stack is:\n\nSystem.ArgumentException: An item with the same key has already been added.\n   at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)\n   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)\n   at Ionic.Zip.ZipFile.InternalAddEntry(String name, ZipEntry entry)\n   at Ionic.Zip.ZipFile._InternalAddEntry(ZipEntry ze)\n   at Ionic.Zip.ZipFile.AddFile(String fileName, String directoryPathInArchive)\n   at Ionic.Zip.ZipFile.AddOrUpdateDirectoryImpl(String directoryName, String rootDirectoryPathInArchive, AddOrUpdateAction action, Boolean recurse, Int32 level)\n   at Ionic.Zip.ZipFile.AddOrUpdateDirectoryImpl(String directoryName, String rootDirectoryPathInArchive, AddOrUpdateAction action)\n   at Ionic.Zip.ZipFile.AddDirectory(String directoryName)",
