When comparing Krusader vs Dolphin, the Slant community recommends Dolphin for most people. In the question“What are the best Linux file managers?” Dolphin is ranked 2nd while Krusader is ranked 8th. The most important reason people chose Dolphin is:
Like other KDE applications, Dolphin makes use of KIO which gives Dolphin access to other APIs and services. For example, it allows Dolphin to manage files stored remotely the same way you can manage local files through FTP.
Ranked in these QuestionsQuestion Ranking
Pro Great two-pane interface
Pro Folder synchronization
Pro Virtual file systems
Search results as example saved into virtual folder and can be accessed later. All file operations may be performed on items in search results as if they were files in single folder.
Pro SFTP support
Pro Handles most archives. There is little difference in behaviour between an archive file and a regular folder.
Pro Searching capabilities and copying/deleting/moving in background
Pro All common operations can be done with keyboard efficiently
In addition, shortcuts can be easily renamed.
Unlike Dolphin and many others.
Pro Many operations like copying and moving files can be queued
Long running operations can be queued.
There is no point in doing them in a parallel way, as speed decreases dramatically.
Pro Multi-rename tool
Pro Can view and edit many files
Even editing a file inside a .zip file.
Has hexadecimal viewer embedded for binary files.
Pro Filename association and instant console availability
Pro Custom commands can be added to the menu easily
And they can use the current folder, the selected files....
Pro Can split views
Dolphin supports splitting the view in two navigational areas, this way you can navigate two different directories at the same time.
Pro Easy to extend with plugins
Dolphin follows KDE's philosophy of being extendable and configurable. It can easily be configured and customized through plugins.
Pro Integrated terminal
Perssing F4 with any opened folder on a mounted path opens a konsole within dolphin.
Pro Auto mounts flash drives
Dolphin automatically identifies and mounts external flash drives.
Pro Immenseley configurable
As with any KDE app, Dolphin, allows adding or modifying toolbar buttons and keyboard shortcuts.
Pro Fast at opening graphics folders
Pictures with or without previews is optional and selectable at the touch of a button.
Pro Also has a refresh option
Dolphin is without a doubt the best fully functional and easy to use and multitask with.
• Dolphin also has a refresh button which no other File manager has. It's great for tracking a large files transfer; that's what file managers are for - good common sense.
Pro Fully supports HiDPI
Supports HiDPI displays.
Con KDE dependencies
If you don't use KDE, you'll be forced to install quite a large amount of KDE libraries.
Con Interface can be overwhelming
Con New releases are infrequent
It can be seen in https://quickgit.kde.org/?p=krusader.git that maintenance work is done in a continous fashion, but no new releases are provided.
Even though it is perhaps the more feature-rich file manager.
Con "Type" column too verbose
Despite having a large enough monitor, If you keep the size of the browser window small, the "Type" column (in "Details" view mode) insists on including the complete multipart MIME string, making the column so wide that trying to limit its width makes the column useless. Sorting by "Type" renders the list into an incomprehensible mess.
Con Maybe a little slow on startup
Dolphin can be a little slow on startup (depending on distro, hardware etc...). Startup time can vary from a couple of seconds to up to a minute.
