    "Html": "Hi Cheeso,\r\n<br>Reposting from the 'C++/CLI and &quot;using&quot; keyword' thread, as requested!\r\n<br>\r\n<br>I'm using DotNetZip in a C++/CLI project to create encrypted and potentially multi-spanned archives, which are written to CD (hence the multi-spanning).  I also have a small app that auto-launches from the first CD, collates the fragments to a directory on the recipient machine's hard-drive, requests the password and decrypts the archive, attempting to clear up the zip fragments after the extraction is complete.\r\n<br>\r\n<br>I'm getting an exception when deleting the spanned zip files after extracting, with the error text as follows:\r\n<br>&quot;The process cannot access the file 'xxxx.z01' because it is being used by another process.&quot;\r\n<br>\r\n<br>I'm using Ionic.Zip.Reduced.dll v1.9.1.5, on WindowsXP\r\n<br>The code is broadly as follows:\r\n<br>\r\n<pre>...\r\nZipFile^ zip;\r\ntry\r\n{\r\n    zip = ZipFile::Read(sourcePath);\r\n    zip-&gt;Password = password;\r\n    zip-&gt;ExtractAll(extractPath, ExtractExistingFileAction::OverwriteSilently);\r\n}\r\ncatch(...)\r\n{\r\n}\r\nfinally\r\n{\r\n    delete zip;\r\n}\r\n\r\ntry\r\n{\r\n    Directory::Delete(sourcePath);\r\n}\r\ncatch(Exception^ ex)\r\n{\r\n}\r\n...\r\n</pre>\r\n<br>\r\n<br>Couple of notes:\r\n<br>1) I've used 'delete zip' rather than 'zip-&gt;~ZipFile()' as this has the same effect and is more idiomatic for C++.  (I tried zip-&gt;~ZipFile() just incase, but get the same results.)\r\n<br>2) If the zip is a single span, it deletes just fine.\r\n<br>2a) To test, I took out the 'delete zip', and I then get the exception even for single span archives, as you might expect!\r\n<br>3) In Windows Explorer I can not delete any of the zip fragments until the extraction application exits.\r\n<br>\r\n<br>So, I was wondering if the Dispose method fails to close the zip fragments when dealing with a multi-span archive?\r\n",
