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.
  • Folder tree (either shared or two separate for dual-display).
  • Tabbed explorer panels.
  • Internal zip

  • Internal FTP handling, including (for a small extra fee) advanced FTP and SSH

  • 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.
  • Preview panel, and preview of thumbnails (including animated avi

  • File collections. These are like virtual folders that contain links to the original files (unlike shortcuts, these actually deal with the files directly).
