While Windows includes basic capabilities for managing archive files such as ZIPs, it lacks support for all other file archive formats. WinArchiver enhances this functionality by accommodating a variety of formats and offering advanced features for creating, editing, and mounting archives.

7-Zip, believe that a lot of people heard of it, but few of us really used, just because we are accustomed to the most common WinRAR and the once - great WinZIP. Anyway, 7-Zip is the one which currently has a extremely high compression ratio archiver (developed by Igor Pavlov from Russia), this also is the most important technical characteristics measure for such applications. In addition, 7-Zip releases based under GNU LGPL , so it is open source and free.
