DotNetZip

This is the latest stable release of DotNetZip.Status: The binaries here are final. All of the bugs listed here are fixed in these binaries. This release has these downloads: DotNetZipLib-DevKit-v1.9.zip - This is probably what you want. This is a ... [More] binary release, that includes of the signed DLLs for Zip and Zlib, for desktop and Compact Framework; the XML Documentation file for intellisense; the help files (CHM & Helpviewer); and the Licenses. Download this if you want to build .NET, COM, or PowerShell apps that use the Zip library. DotNetzip-src-v1.9.x.x.zip - the source code for the Zip & Zlib Libraries, the setup (msi) project, the test code, and a bunch of examples. Download this if you want to peruse or modify the source, or extend the example utilities. DotNetZipLib-Runtime-v1.9.zip - a binary release, that includes the signed DLLs, and the Licenses. Download this if you want to distribute .NET applications that use the Zip library, on the desktop or on the Compact Framework, or if you want to run a .NET application that depends on this library. DotNetZipLib-Silverlight-v1.9.zip - a binary release, that includes the the Silverlight version of the signed DLLs, and the Licenses. DotNetZipUtils-v1.9.zip - a set of exe tools (command-line and GUI) that rely on the library, to create and manage zip files. Download this if you want finished user-level tools to manipulate zip files. (A replacement for WinZip) DotNetZipUtils-v1.9.msi - an installer for Windows for the Zip utilities that utilize the library. This is the same stuff as the DotNetZipUtils-v1.9.zip, but in MSI form. It optionally sets up file associations, guides you through the install. DotNetZip-Runtime-v1.9.msi - an installer for the runtime. DotNetZip-Documentation-v1.9.zip - the Documentation. There's a CHM file as well as a HelpViewer 1.0 format. They contain the same information, just in different formats. Notable: the quality/reliability of the code is much higher than for v1.9.1.5 - many bug fixes. New bzip2.exe tool, and a gzip.exe tool. Silverlight DLLs for ZIP, ZLIB or BZIP2 are included more than 60 new tests The version numbers for these preliminary DLLs is currently v1.9.1.6 The minimum requirement for the binaries is (as in prior releases of DotNetZip) .NET 2.0 or later. To build the source you need VS2010 and .NET 4.0.

This is the latest stable release of DotNetZip. Status: The binaries here are final. All of the bugs listed here are fixed in these binaries. This release has these downloads: DotNetZipLib-DevKit-v1.9.zip - This is probably what you ... [More] want. This is a binary release, that includes of the signed DLLs for Zip and Zlib, for desktop and Compact Framework; the XML Documentation file for intellisense; the help files (CHM & Helpviewer); and the Licenses. Download this if you want to build .NET, COM, or PowerShell apps that use the Zip library. DotNetzip-src-v1.9.x.x.zip - the source code for the Zip & Zlib Libraries, the setup (msi) project, the test code, and a bunch of examples. Download this if you want to peruse or modify the source, or extend the example utilities. DotNetZipLib-Runtime-v1.9.zip - a binary release, that includes the signed DLLs, and the Licenses. Download this if you want to distribute .NET applications that use the Zip library, on the desktop or on the Compact Framework, or if you want to run a .NET application that depends on this library. DotNetZipLib-Silverlight-v1.9.zip - a binary release, that includes the the Silverlight version of the signed DLLs, and the Licenses. DotNetZipUtils-v1.9.zip - a set of exe tools (command-line and GUI) that rely on the library, to create and manage zip files. Download this if you want finished user-level tools to manipulate zip files. (A replacement for WinZip) DotNetZipUtils-v1.9.msi - an installer for Windows for the Zip utilities that utilize the library. This is the same stuff as the DotNetZipUtils-v1.9.zip, but in MSI form. It optionally sets up file associations, guides you through the install. DotNetZip-Runtime-v1.9.msi - an installer for the runtime. DotNetZip-Documentation-v1.9.zip - the Documentation. There's a CHM file as well as a HelpViewer 1.0 format. They contain the same information, just in different formats. Notable: the quality/reliability of the code is much higher than for v1.9.1.5 - many bug fixes. New bzip2.exe tool, and a gzip.exe tool.

This is DotNetZip v1.9. It is the latest stable release. The current version number is v1.9.1.5, released 2010 February 25. New features: Parallel deflate, to optimize the Zip library to use multi-processors Support Asynchronous Operations ... [More] create and read multi-part zip files. Allow setters on ModifiedTime, AccessedTime, CreationTime Make traversal of NTFS Junctions optional in AddDirectory Expose IsZipFile method to COM clients Add support for optionally traversing directory junctions in WinForms app Allow writing into ZipEntry stream (WriteDelegate) implement ZipOutputStream Implement a ZipInputStream Self Extracting EXE - optionally remove files after running "post unpack exe" Environment Variable substitution on the default extract location of SFX Deliver DotNetZipLib Help so that it can be integrated into VS2008 Notable fixes: Zip Tool and File associations Remove obsolete methods and properties Can't unzip on the Mac, when the zip was written to Response.OutputStream and includes a folder Zlib exception when compressed stream size is (multiple of buffer size) + header size +(0 to 7) Public key token differs between ILMerge'd DLLs and regular DLLs There are some breaking changes from v1.8: the SaveSelfExtractor() methods have been consolidated. They use the new SelfExtractorSaveOptions class. All the interfaces marked Obsolete in v1.8 have been removed. These include: the methods on the ZipFile class: AddFileFromStream(), AddFileStream() UpdateFileStream(), AddFileFromString(), all the Extract() methods that accept an entry name, and the ExtractAll() method that accepts a boolean; on the ZipEntry class, the Extract() methods that accept a Boolean, and the OverwriteOnExtract property, as well as the SetNtfsTimes() method. For FxCopy compliance, the properties on the ZipEntry called Atime, Mtime, and Ctime have been replaced with AccessedTime, ModifiedTime and CreationTime. The WantCompression callback has been removed. There is a SetCompression callback that can be used in its place. The ReadTwiceOnInflation callback has been removed. It's no longer necessary now that DotNetZip uses zlib. The ForceNoCompression property has been removed as redundant. Use CompressionLevel instead. The public key used on some of the assemblies has changed. (See workitem 8819) The ZipFile.AddEntry and UpdateEntry methods that accept a directoryPathInArchive have been modified. Features being deferred to the next release: Asynchronous Programming Model for DeflateStream/GZipStream/ZlibStream Silverlight support expanded COM support: events, zlib, etc. There will also be fit-and-finish changes and bug fixes. I would also expect a few smaller, tactical features.
