My Top Freeware/Open-source List Mainly for Windows
Compression/Zip Tools:7-Zip | www.7-zip.org | 7-Zip is an open source archiver with a hihj compression ratio, really makes Windows built in zip feature useless. It also does everything WinZip does minus the fancy interface and pricetag.
jZip | www.jzip.com | A free WinZip alternative based on 7-Zip so it works about the same, they also have an affiliate program so maybe there is a paid version.
PeaZip | http://sourceforge.net/projects/peazip/?source=dlp | PeaZip claims to open up to 150 different kinds of compressed files which is grate but I'm not testing that, and it has a portable version which requires no installation at all. It also has a random password generator amd secure delete. (best review: http://www.pcworld.com/article/2044863/review-peazip-5-decompresses-everything.html)
Hamster Free Zip Archiver | | Aside from the fancy interface it works the same as the rest but if your looking for a more modern GUI then this is the one for you.
