Pro Caja script extension makes it more useful
Caja script extension adds your script in script menu, then passes the file name as a parameter. This allows you to run operation which is not included in Caja.
Pro Allows you to access remote or local locations
You can click the Files entry in the panel to access a specific location (remote or local), connect to a certain server (FTP, SFTP, SAMBA, etc.), access your bookmarks, open a new window, as well as to change its default functionality.
Pro Easy to configure
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 Handles most archives. There is little difference in behaviour between an archive file and a regular folder.
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 All common operations can be done with keyboard efficiently
In addition, shortcuts can be easily renamed.
Unlike Dolphin and many others.
Pro SFTP support
Pro Multi-rename tool
Pro Custom commands can be added to the menu easily
And they can use the current folder, the selected files....
Pro Searching capabilities and copying/deleting/moving in background
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
Con Frequently very slow to transfer multiple small files
Folders move fine, but it chokes on files, where other browsers take seconds.
Con Mostly unconfigurable
There are not many ways to configure Caja to fit your needs. Besides what can be seen in the settings button you can't configure it further.
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.
