With WinRAR, you can unzip contents from archived or zipped folders. You can also create your own archived folders, and password protect them. The program is especially useful if you need to disseminate large files over the Internet. The WinRAR software will compress those files to reduce their size and then zip them into a folder. WinRAR is free to download for a trial period, after which you must activate the software to continue to use it.
