IZArc is still good software. I wrote awhile back about this compression utility that replaces WinZip, 7-Zip, WinRAR, and any other file archiver you may use. It's free, fast, and has great Windows shell integration so you almost never need to actually use the GUI. All you could want.
For some reason no one seems to know about this program, so I'm writing about it again. The homepage is currently featuring a heartbreaking plea for donations so he can afford to buy a copy of Visual Studio 2005 and release a Unicode version of IZArc. If you happen to work in Microsoft dev relations maybe you can find a free copy to ship him?
