'''Directory Opus''' (or "DOpus" as its users tend to call it) is a [[File manager|file manager program]], originally written for the [[Amiga]] computer system in the early to mid-1990s. Commercial development on the version for the Amiga ceased in 1997. Directory Opus is still being actively developed and sold for the [[Microsoft Windows]] operating system by GPSoftware and there are open source releases of Directory Opus 4 and 5 for Amiga.

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 Potter joined with Greg Perry and the Australian-based GPSoftware to continue its development, and has since been published by GPSoftware.

==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 feedback given by its users. Some of the features include:
*Single or dual-panel exploring.<ref>{{cite magazine|last=Mendelson|first=Edward|author-link=Edward Mendelson|date=2004-06-08|title=File Managers|magazine=PC Magazine|publisher=Ziff Davis|issn=0888-8507|volume=23|number=10|page=132}}</ref>
*Folder tree (either shared or separate for dual-display).
*Tabbed explorer panels.
*Ability to maintain date created/modified timestamps for both files and folders.<ref>{{cite magazine|last=Rubenking|first=Neil J.|date=2006-04-11|title=Incredibly useful utilities, Directory Opus 8|magazine=PC Magazine|publisher=Ziff Davis|issn=0888-8507|volume=25|number=6|page= |pages=98–99}}</ref>
*Internal handling of [[ZIP (file format)|ZIP]], [[RAR (file format)|RAR]], [[7Zip]] and other archive formats (browse them like folders).
*Internal [[FTP]] handling,<ref>{{cite magazine|last=Mendelson|first=Edward|author-link=Edward Mendelson|date=2005-02-08|title=Replace Windows Explorer|magazine=PC Magazine|publisher=Ziff Davis|issn=0888-8507|volume=24|number=2|page=46}}</ref> including (for a small extra fee) advanced [[FTP]] and [[Secure Shell|SSH]] (browse these like folders also).
*Internal [[Media Transfer Protocol|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.<ref>{{cite news|last=Harac|first=Ian|date=2014-03-31|title=Directory Opus 11 review: The premier file manager for power users|url=http://www.pcworld.com/article/2137351/directory-opus-11-review-the-premier-file-manager-for-power-users.html|newspaper=PCWorld|access-date=2017-05-16}}</ref>
*Powerful file selection and renaming tools, with advanced [[regex]].
*User-definable toolbars, menus, filetypes and filetype groups.<ref>{{cite magazine|last=Mendelson|first=Edward|author-link=Edward Mendelson|date=2005-05-24|title=File Managers|magazine=PC Magazine|publisher=Ziff Davis|issn=0888-8507|volume=24|number=9|page= |pages=92–93}}</ref>
*Preview panel, with preview of thumbnails (including animated [[Audio Video Interleave|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).
