The program includes an interface different from that of the 7-Zip's. J7Z is actually based on 7-Zip and, as a result, it is very intuitive and easy to use. You have all the options at just a click away.
Of course, J7Z is integrated into Windows' context menu. You can compress files by simply right-clicking them and then choosing the corresponding option. It is all very fast and convenient.
J7Z is an excellent compression and decompression tool. In addition to being fast, it perfectly integrates into Windows.
