PeaZip

PeaZip is a powerful but easy to use open source archiving tool. There are many free compression utilities out there, but few are as robust as this one. In many ways, it is more powerful than some paid archive apps. The program is user friendly. Thanks to its drag and drop support, a user just has to drag a zip file on the interface and it will be decompressed. The archiving screen pops open when you drop a file there. All the basic functions are labeled clearly so new users will have no trouble using the program. File browse tools and function buttons make it a snap to add folders and files.
