Convert tar.bz to arj

What is the difference between .tar.bz and .arj?

Description: This is a compressed archive in the TAR container with the help of the BZIP tool. It was created for use in Unix systems. The TAR container combines several files into one archive that’s placed in a TBZ compressed file. They’re used as installation packets in the installers of some operating systems.; The ARJ Compressed File Archive (.arj) is a file format used for data compression and archiving. Developed in the early 1990s by Robert Jung, ARJ stands for "Archived by Robert Jung". The format allows for efficient compression of files, supporting multi-volume archives, which means a large archive can be split into several smaller files for easier management and distribution. It also supports a high level of encryption for secure data storage.
