Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Good all-purpose file manager
Pro Faster than most similar applications
It's hard to find a free or low cost alternative that is as quick, and stable, especially managing NTFS volumes on a remote NAS. It still freezes and chokes, just not as often as newer applications, like XYplorer, Free Commander, etc.
Pro 250+ file attributes that can be added as columns to view more file attributes
Pro Comprehensive functionality
Full search, sync files & folders, show folder sizes, robust copy, native file viewer, tabs within panes, very configurable display, command shell, bookmarks, etc.
Pro Ability to save state
xplorer² gives users the ability to save the state, so the program will open with the same state the next time it's used.
Pro Execute DOS commands
Pro Flexible search function
Search based on numerous file attributes. Search in ranges. Search inside files. Save search parameters for future use.
Pro Browse Flat to view the contents of several subdirs as if they were stored in a single dir
Let's say you are located in a given subdir that has 5 subdirs. You can see the contents of all the files located in those subdirs as if they were stored in a single dir. Very useful when you want to locate files that you don't know exactly where they are located and searching is not an option.
Pro Free version available
There is a free version available, xplorer² Lite, for non-commercial use.
Pro Scrap Area where you can drop files located in different sub directories to allow you to access them instantly
Let's say that today you are going to update a letter located in subdir X, continue developing a spreadsheet located in subdir Y, review a presentation located in subdir Z, review a project located in subdir W, etc.. You can drag and drop all these files to the Scrap Area and open and work with them, save them, open again, continue tomorrow and the files will be updated in their respective original locations. No need to navigate and navigate and navigate.

Cons
Con Stagnating rate of development
Any improvements to the software are happening at a glacial pace which is making this software more and more outdated for a long time now.
Only a few minor improvements a year. User suggestions for improvements are routinely rejected or explained away. As for suggesting new features -- you'll quickly abandon all hope. Only realistic reason to visit their support forums is to read Kilmatead's posts -- for anything else prepare to be disappointed.
UPDATE (and slightly offtopic): Kilmatead seems to be no longer active on the forums, so the next best thing is xplorer2 blog which seems to often feature interesting technical topics.
Con Un-evolved
The interface is essentially unchanged since its Windows XP days, with very little customization possible. Organization of features is convoluted, with some simple ones, like individual icons to quickly switch views missing. The stagnant cluttered design can make even long-time users drop the program.
Con Distracting prompts in the Lite version
A free version of the program is available, xplorer² lite. However it is very light on features, and will display a prompt if a feature is selected that isn't available in the Lite version.
The full program is $29.95 for advanced and $49.95 for max power.
Con Cannot access Android device connected by USB
Con Cannot access Android device by FTP
And can never will as this is clarified by developer that this feature will never be added.
Con It doesn't have UNDO function
Very important. When you work with valuable data files, this function can't be ommited.
Con Navigating folders by Ctrl+Tab has considerable delay
Con Folders cannot be sorted by size
Con Browsing Recycle Bin is very slow
Navigating away from Recycle Bin tab and coming back to it reload the Recycle Bin which is very slow as mentioned. Program has an option to open recycle bin in Windows File Explorer, which suggests that developer is aware that opening Recycle Bin is problematic.
Con Confusing
Con Context menu only based on icons
