I have not checked SharpZip, but Ionic.Zip supports streams. I use it to create ZIP64 encrypted files on memory and send them to a web server without never writing a file. It also supports Gzip, dunno about Bzip2. The LZMA SDK of 7-Zip works also on streams. I have not checked for audio, video or PDF, but I'm pretty sure that Tao.Framework (for audio and video using ffmpeg library, not pure C# but fully multiplatform) uses streams, and I know there is a PDF viewer and creator C# library, pure C#, no external dependencies. _______________________________________________ Gtk-sharp-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/gtk-sharp-list
