I just discovered today when saving files to an archive, that the NTFS file attributes are all cleared from the source files. Several of the files I'm archiving need the read-only attribute set to work properly. I've looked through the documentation and don't see anything about leaving the source file's attributes unaltered. What is interesting is when I extract the files, the archived files do have these attributes, so I don't understand why the original file would lose these. Any idea what causes this?</p>\r\n<p><br>I call the AddDirectory method for adding files to an archive and use the following signature:</p>\r\n<p>\r\n<div style=\"color:Black;background-color:White\">\r\n<pre>ZipFile.AddDirectory(<span style=\"color:Blue\">string</span> directoryName, <span style=\"color:Blue\">string</span> directoryPathInArchive)\r\n</pre>\r\n</div>\r\n</p>\r\n<p>&nbsp;</p>\r\n<p>I'm using version 1.8.4.24 of the full library (Ionic.Zip.dll)</p>\r\n<p>&nbsp;</p>\r\n<p>Thanks,</p>\r\n<p>Jim</p>",

I was copying the source folders to a backup directory in a separate thread which was clearing the file attributes. I thought I commented out everything associated with that folder copy operation, but turns out I did not.</p>\r\n<p>&nbsp;</p>\r\n<p>Thanks again.</p>\r\n<p>&nbsp;</p>",
