It also includes features such as error recovery, which allows the program to recover from data corruption or errors during the compression process. ARJ stores the compressed data in an ARJ file, along with metadata about each file, such as its name, size, and permissions. ARJ files can also include multiple files, allowing them to be used for archiving purposes.

Advantages of ARJ

There are several advantages to using ARJ for data compression and archiving:

• ARJ is highly effective at compressing files, often achieving better compression ratios than other popular algorithms such as ZIP and RAR.
