A .arj extension file is a file that is compressed using the ARJ archiver. The program was developed by Robert K. Jung and hence the extension .arj stands for Archived by Robert Jung. ARJ was initially developed in 1990 for DOS and for the earlier versions of Windows. It was a very popular format for compression in the early days because it was very efficient at file compression. It was highly popular at the time of early networks. It is fast, reliable and helps to save on disk space.
The .rar filename extension is a popular and partially open archive file format associated with the compression and decompression tool WinRAR. The format was developed by Eugene Roshal with its initial release in 1993. It, like many other archive formats, acts as the compressed data container for one or several files. The archive format can maintain the directory structure of the compressed archive even when unpacked to a directory. The RAR file format supports multi volume file compression where an archive is saved as a sequence of several files of a given size.

The .arj file format supports data integrity protection, multiple volume archives, file version management, long file names acceptability, configurable options for commands and ANSI based escape sequence for display handling. This format is used to create high-efficiency archives of compressed files. The .arj file extension has advanced features which made it easy to split up a single archive into small chunks.
The RAR archive format supports compression, file spanning, and error recovery. Compression is carried out using a prediction by partial matching algorithm and the lossless compression algorithm LZSS. The RAR file format has a range in file size from as low as 20 bytes to 8 exbibytes less 1. It also supports AES encryption at 256bits as well as the CRC32 checksum and BLAKE2 file hash algortihms.
