    "Description": "WinZip interprets an OS encoding of 10 in the  Version Made By field as \"Tops-20\" not NTFS as per the appnote.txt spec.\n \nDotNetZip currently encodes 10 in that place, and this is causing incompatibility. \n \nA while ago, DotNetZip always used 0 for the upper byte of the \"version made by\" field, just like WinZip. Then someone asked for file attributes to be encoded into the zip, and also properly applied upon extraction. (workitem 7071)  The meaning of the file attributes field depends on the value of the \"Version made by\", and specifically on the encoded OS version.  So I modified DotNetZip to store and set the NTFS file attributes, and also encode NTFS in the \"version made by\" field.\n \nAt least I thought they were NTFS attributes. Turns out the attributes returned from File.GetAttributes() are not NTFS attributes but are FAT attributes, and Version Made By should be zero, as WinZip has it.  (This isn't quite true - the value returned from File.GetAttributes includes attributes that apply to FAT, and also may include some attributes that are supported only on NTFS.   But I can special case those.) \n \nSo I think we can do what rmlewin suggests - encode 0 for the OS, and keep DotNetZip compatible.",
