myReview

I have try 7-Zip, ZipGenius, IZArc for my compression software and 7-Zip is the one that I like best. Maybe for other user prefers IZArc or ZipGenius because it has a better interface. I like 7-Zip because it is faster than other free compression software and almost like WinRAR in comparison to commercial software. Highly recommended for file compression. Their new .7z file compression have have less file size than .zip or .rar.
