Directory Opus

Directory Opus is a 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.
Folder tree.
Tabbed explorer panels.
Ability to maintain date created/modified timestamps for both files and folders.
Internal handling of ZIP, RAR, 7Zip and other archive formats.
Internal FTP handling, including advanced FTP and SSH.
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.
User-definable toolbars, menus, filetypes and filetype groups.
Preview panel, with preview of thumbnails.
File collections. These are like virtual folders that contain links to the original files.
