Just to add some context, as far as I remember, gentoo was pretty similar to how DOpus worked on the Amiga until version 5, when it went from being a classic "one window, two pane, rows of buttons" thing, to arbitrary numbers of independent windows. DOpus 5 was really neat and powerful but also quite a different experience, more like its own desktop environment really. I hope I still have the ring bound manual somewhere...

Given a month of time, I don't think I could express the vast differences between Directory Opus 12 and Gentoo or many other file explorers that are available. Even PathFinder on macOS is a pale shadow of what Directory Opus achieves, and I happen to love PathFinder.

From file type support, to file renaming, image sizing, meta data options, scripting, macro recording, tabbed directories, filtering, finding in files, finding files in diretories, directory navigation, bookmarking, stability, speed, virtual directories, directory browsing, file system search, ftp, sftp, one and two way syncing, filename copying (e.g. copy filenames, copy full pathnames, copy short names, copy short pathnames, copy URLs, copy MD5 checksums, copy SHA-1 checksums, copy full pathnames with double backslashes, copy folder path, copy complete folder listing), file copying & file moving, queued file copying, unattended file copying, speed of file copying, prioritized file copying, pausable file copying, file deduping, renaming of dupes, unzipping and zipping in different archive formats, encoding files and decoding files. And I've only scratched the surface. And then just general spit and polish. And compatibility with all the different versions of Windows. And everything on a hotkey. And everything with configurable & saveable preferences.

I know that "but <favourite file explorer> also does that!" is a common refrain, but on Directory Opus, whatever feature you are comparing against, Directory Opus basically took the amplifier knob, turned it up to 11, then snapped it off to make sure you couldn't fuck with it. I know that "there is a utility in Linux that does that" or "well, that's easy, you just have to open a terminal and..." but again, it's built-in to Directory Opus. It just works.

I know I am singing high praises of this software, but it is like comparing Photoshop and GIMP, they both push pixels, but we know deep down, there really is no competition.

I really wish GPSoft would consider a Linux port, but they have emphatically stated that they have no intention of doing so, for business reasons, and I can kind of see their point.

There's nothing bad about Gentoo, but it isn't Directory Opus.
