CAB

Windows Cabinet File

The cabinet file format, shortened CAB, is an archive file format that was developed for the Microsoft Windows operating system. The format supports the lossless family of data compression algorithms as well as embedded digital certificates that facilitate data integrity. Archives created using the CAB format have the filename extension .cab and are recognized by the operating system through the identifying 4 bytes in the header. CAB enjoys support by other Microsoft technologies such as the Setup APIs, Windows Installer and others. In fact, some earlier integrated development environments developed by Microsoft could create setup files that were organized as CAB files.
JAR

Java Archive File

A .jar extension file is a Java Archive format file that is used to store a large number of files into one single file. The basic advantages of .jar extension files are data compression, archiving, decompression, unpacking of the archived file and electronic signing which is one of the advanced features of this format. The Java Development Kit (JDK) contains the Java Archive Tool that is used to perform the basic tasks on .jar extension files. The JAR format is similar to a ZIP file format and it was specifically developed to help download Java applets and its components that include class files, images and sounds in one single HTTP transaction.

A .jar file contains the Java source code, a manifest file, XML based configuration data, JSON-based data files, images and sound clips as well as security certificates. These files use a standard compression algorithm and hence can be easily opened by extracting the contents of the file with a standard decompression tool like the tool used to extract .zip extension files.
