Directory Opus vs nnn

Directory Opus has no write-up on Specifiction yet; its figures are above.

nnn is a terminal file manager designed to be small, fast and nearly zero-configuration. It handles copying, moving, deleting, archiving and linking selections, alongside batch renaming, disk-usage analysis, app launching and file picking. Navigation includes contexts, sessions, bookmarks and directory marks, while search options include instant filtering, fuzzy matching, regular expressions and string filters. It provides directory and text previews, and can create, list, extract and mount archives. Plugins can add functions such as live previews, disk mounting, file comparison and uploads. Remote mounts require optional sshfs or rclone dependencies. The project says nnn typically needs less than 3.5 MB of resident memory; it has no configuration file and uses defaults, with optional environment-variable settings. It is free and open source under the BSD-2-Clause license, and is listed for Android, Linux, macOS and Windows. The project offers packages and a statically linked binary, or users can compile it from source.
