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.

Features

Directory Opus has evolved since its first release in 1990 as a basic two-panel file manager. The interface has evolved significantly due to the amount of feedback that the users have given it. Some of the features include:

Single- or dual-panel exploring.^[2]
Folder tree (either shared or two separate for dual-display).
Tabbed explorer panels.
Ability to maintain date created/modified timestamps for both files and folders.^[3]
Internal handling of ZIP, RAR, 7Zip and many other archive formats (browse them like folders).
Internal FTP handling,^[4] including (for a small extra fee) advanced FTP and SSH (browse these like folders also).
Internal MTP handling for portable devices like phones and cameras.
Flat-file display, where you can flatten a folder tree, and even hide the folders themselves.
Powerful file selection and renaming tools, with advanced regex if needed.
User-definable toolbars, menus, filetypes and filetype groups.^[5]
Preview panel, and preview of thumbnails (including animated avi thumbnails).
File collections. These are like virtual folders that contain links to the original files (unlike shortcuts, these actually deal with the files directly).
