To open an archive simply double click (or, you're working in Web style, click once)
on an archive listed in My Computer or the Windows Explorer, drag and drop an
archive onto IZArc, or use the standard Open dialog box. The main IZArc window features a list with the names, and sizes of all files in the open archive. This list
can be scrolled and sorted on any field. A configurable tool bar provides fast access
to commonly used actions. Extensive context sensitive help is always available
