Don't know if this is the right section, but I stumbled on this TOTALLY FREE utility that completely replaces WinZip and WinRAR. It's a very powerful archiver loaded with useful features. There's no nag screen or anything, the software is 100% freeware. It's called IZArc.
Download Here. It's the only free archiver I know of that opens zip, RAR and many other files for free.
Features (From IZArc Site):
· Add files to an existing archive
· Delete files from an existing archive
· Extract files from an existing archive
· Test an archive file
· Convert archive
· Repair broken archive
· Searching for any files in many archives
· Favorite Folders
· Obtaining a detailed list of files and information like compression rate, path, or size from an archive file
· Supports both long and short 8.3 filenames
· Split an archive file into multiple parts of a specified size
· Disk spanning from and to multiple diskettes or other removable media
· Implementing the possibility to sort the list items by name size, date and etc.
· Full Drag & Drop support
· Integrating in Windows Explorer context menu
· Automatic installation of most software distributed in archive files
· Add/View comments in an archive
· By double-clicking onto a file in the file list, it's opened with the program associated to this file type
· CheckOut feature
· Create a self-extracting archive
· E-mail an archive

I thought this utility was a gem and I thought I'd share it with everyone
