High Quality Content by WIKIPEDIA articles! Directory Opus (or "DOpus" as its users tend to call it) is a popular file manager program, originally written for the Amiga computer system in the early to mid 1990s. Development on the Amiga version ceased in 1997, but an entirely re-written version of Directory Opus is still being actively developed and sold for the Microsoft Windows operating system by GPSoftware. Directory Opus was originally developed by, and is still written by, Australian Jonathan Potter. Until 1994, it was published by well-known Amiga software company Inovatronics, when the author joined with Greg Perry and the Australian-based GPSoftware to continue the development of the product, and it has been published by GPSoftware ever since.
