Essential System Tools: Krusader – KDE file manager

Last Updated on May 28, 2022

Summary

Krusader is the perfect file manager if you are running KDE Plasma 5. It’s an all-in-one, very powerful, flexible and fast file manager. And it’s faithful to the text mode operation of Midnight Commander, while at the same time exploiting the benefits of a GUI environment.

The user experience is not as good with other desktop environments. For example, under GNOME we experienced application crashes when running the disk usage tool. And it’s more cumbersome to get everything up and running. For example, trying to manage bookmarks fails as keditbookmarks was not installed on our GNOME based distro. The same applies when we tried to start a terminal. Krusader tries to start up konsole which, like keditbookmarks, was not present.

I have used Krusader in the past. The only reason that I have it installed now is because of the removal of root functions from Dolphin! I always have a separate data partition on my computers. When doing a fresh install, or a re-install, I create the data partition, but is is created as being owned by root, not my user. In the past, Dolphin had the ability to allow me to change the ownership of a directory or partition. However, the author of Dolphin made the stupid mistake of removing that functionality. Now I run Krusader as root to change properties when I need to.

GUI software should *not* be run as root. It’s simply not secure. Even if you are happy to run that security risk, it’s only right and proper that software developers make the right decisions for the majority.

Configuration Page 9 should be with Page 1 or Page 2 as this what opens after install

Several years have passed since that article was written, situation is better, although (for example, for the keditbookmarks case) we still can see on (for example) packages.ubuntu.com/lunar/krusader some suggested and recommended packages that Krusader may need to use.
