JZip and 7 Zip are among the most popular archive compression formats. Similar to PAR and RAR, these types of archives also contain multiple files that have been compressed in order to cut their file size. However, these formats don't allow you to directly edit the files that they contain, rather you must either open the individual files or the archive as a whole by using the "edit" function. You also cannot rename the files within the archive.
Another option that is available for extraction of jZip and zipeg is the "tar" archive. The archive created with the help of tar is very similar to the zip archive and quite often these archives are used by users to extract data from zip files. However, when you try to use the "tar" archive, you will realize that the files extracted are in the form of binary format. To extract them, you need to convert them to a text format using "bzip2" application. However, if you want to extract the entire jZip file, you need to use "rar" application.
Using archive like 7-zip and jZip is fairly easy. You just need to download one from the internet, install it and then follow the instructions provided. In fact, many software development companies offer a similar utility, which is based on the jZip and rar technology. Just go for a reputable company to extract your data and enjoy your multimedia experience.
