What is a good commercial tar stream lib for c# and .net?
We are currently using SharpZipLib but since it uses the GPL we need to replace it with a commercial lib. See my comment about #ziplib on the main post... but if you really need a commercial product (not open-source), IP*Works! Zip .NET might fit the bill. It does have TAR support according to this . Have you looked at DotNetZip ? It is not under the GPL, but rather the Microsoft Public License (Ms-PL). Just FYI. There is an option to use BSD licensed library for tar reading/writing. Gzip compression and decompression you can do with build-in GZipStream from microsoft .NET 2.0 http://code
