Release Notes

This is the latest stable version of DotNetZip, v1.8.4.31.

DotNetZip is free, but donations are welcomed. Your gift goes to charity. http://cheeso.members.winisp.net/DotNetZipDonate.aspx

New features in v1.8 (workitem noted where applicable):

7803: Extract entry without embedded Path
7366: Make DotNetZip COM-Friendly, so that it can be called from Javascript, PHP, Perl, etc
7241: Better options for selecting Extract behavior when files already exist
7192: Allow app to deliver input stream before writing an entry to the archive
7072: File filter support for including or excluding files when calling AddXxx() and Extract()
7159: Provide a GZipStream to replace the .NET BCL class
7067: DotNetZip SFX should be readable by DotNetZip Also, UI tweaks in the SFX.
Improvements in the WinForms Zip tool. Now supports extract as well as create. It can be used as a replacement for WinZip. It gets set as the default "Open" tool for zip files in Windows Explorer when you install via the MSI. Also, myriad UI improvements, like drag-n-drop. Exploits the new file selector capability: eg, extract *.xml files via the UI.
CLS-compliance on Ionic.Zlib.dll
7071: Properly set File Attributes when Zipping and Extracting
6878: Support NFTS file attribute extensions in ZIP files
now sets LastMod time on Extract() on .NET Compact Framework
7191: Can you set the icon of the Zip Package?
5470: Include a "execute on unpack" option for self-extracting zips.
7907: Need Add event
8093: Add support for extended timestamp field (InfoZip compatibility)
8124: Make it optional to emit Windows and Unix times when saving a ZIP file.
The Zip Reduced library is now marked as CLS Compliant and APTC
DotNetZip now ships both a RELEASE dll and a DEBUG dll. The RELEASE build is significantly faster than the DEBUG build.

There are some breaking changes from v1.7:

CompressionLevel enumerations have changed to be FxCop-compliant. Eg, BEST_COMPRESSION has been replaced by BestCompression, LEVEL3 has been replace by Level3, and so on. Also, the CompressionStrategy enumeration also has similar changes.

Other notable changes:

The use of temporary files has changed: Now, the library creates a temp file in the same directory as the final zip file. Previously the library used the user's temp directory. Apps can still override this with the ZipFile.TempFileFolder property.

Great library, flexible and intuitive + it works. The source code (and Cheeso) are also superb resources.

Huge Library for me!

Wow this thing is great. I needed to unzip password protected files. No problem. Just set the password parameter. In less than 5 minutes I was done coding.

It's very simple to use. And... I found a little bug and after 3 days was fixed! Thanks!
by topas on Jul 27, 2009 at 7:07 AM

The best compression library freeware available on the net. First at all very easy to use and till now i don't have found bugs. Good Work !
by nervoux on Jul 22, 2009 at 9:12 AM

Works great for me.
by timwri on Jul 9, 2009 at 7:54 PM

I don't usually give ratings, but this one deserves an exemption: Nothing, not competing OSource and not even the two well known commercial products, is so clear, simple, straightforward, fast, un-buggy, and good as this library. Its also extremely well documented, and cleanly coded. Any special request gets the fastest response from Cheeso, and usually with a prompt fix, added to the build.
by pashute on Jul 9, 2009 at 12:14 AM

DotNetZip is easy to use and flexible for current zip formats. Kudos to Cheeso - you rock dude.
