Convert 7z to arj

What is the difference between .7z and .arj?

Description: A 7Z file is a type of compressed archive that uses the open-source LZMA compression algorithm to reduce the size of the file. This type of file is often used to store multiple directories and files in a single, compressed package. 7Z files can also include strong AES-256 encryption for added security. They are commonly created using the 7-Zip utility developed by Igor Pavlov.; 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.
