File type: ARJ Compressed Files
The ARJ file extension is used by the compression utility to reference the compressed archives generated by the application.
ARJ is basically an acronym for Archived by Robert Jung in obvious reference to its developer.
This compression tool first made its way into the IT market during the Disk Operating System days. Up to the earlier versions of the Microsoft Windows Operating System environment.
With the inception of the more advanced Graphical User Interface (GUI) Microsoft Windows 95, the ARJ32 version of the compression tool started. This 32-bit console version remained very popular until the Microsoft Windows 2000 platform.
This compression tool was primarily noted for its creation of highly efficient compressed archive files that support the 16- and 32-bit computing architecture of the Intel processor. ARJ became one of the only two mainstream archiving utilities for the MS-DOS and Microsoft Windows Operating System platforms in the middle of the 1990s.
PKZIP compression utility was the main competitor of the software during that era.
