The most stylish among all FMs.
Ranked in these QuestionsQuestion Ranking
Pro Multi-platform (Linux, Windows, MacOS X)
you can use same tool in all desktop OS enviroments
Lots of options allow you to configure DC the way it suits you best: Tools, Fonts, Colors, Hotkeys, Mouse, Fileviews, Plugins, Layout, Toolbars, Tabs, Icons etc.
Pro Powerful tcmd-like search tool (alt+F7)
Pro Directory Hotlist
Save shortcuts to folders. Organize them in a treeview with submenus. Define a name and sorting for each entry.
Pro Source code is available (true free software)
If the developer loses interest there is at least the possibility that someone else will pick up the torch.
Pro tcmd-like multi-rename tool (CTRL+M)
Pro DC uses TCmd plugin API
so you can use documentation from Total Commander for writing plugins. WCX (packer), WDX (content), WFX (file system), WLX (lister)
Pro Closely follows TotalCommander UX
For instance, the 'Settings | Layout' pane is quasi-identical to TCs.
Pro It's that good, you can replace tcmd on windows too
Pro Very sophisticated
Although it is lightweight and simple to use, it can do very sophisticated tasks, like copying files from directories which have a certain extension or file size or have a certain text pattern in them. Also, it's very customizable and stable.
Pro Source Code written in (Object) PASCAL
It's all a matter of perspective. I'm not for an argument about IDE's, frameworks etc, but to me that's a big plus. I think it should be a tie, it's either a pro or a con or should that be neither a pro nor a con. It just depends on context.
The most stylish among all FMs.
Pro Easily open as root
Option to open folder as root from within the right click menu.
Pro Easily open file location in terminal
Option to open a folder in terminal, which can help executing commands such as bash.
Nemo can be extended to have additional features through third party plugins.
Pro Supports bookmarking
You can bookmark folders that you open often, this way you can easily access them from anywhere while using Nemo.
Pro Has dual pane functionality
This functionality was removed in Nautilus and Dolphin at least in Ubuntu-Gnome, but Nemo kept this option, making the obvious functionality of cut, copy and paste much easier.
Pro Double pane and search by name capabilities
Pro Queues file operations
Pro Good networking options
Supports ftp, ssh and samba connections.
Con Apparently only one developer
Con Much slower on Linux and Mac than on Windows
Con Can't edit files on remote FTP servers
Con Source code written in Pascal language
But this does not affect users negatively. It's just programmers problem
Con Changing the background color or font type for customization is not practical
You have to do it with finding and editing the relevant CSS files. No buttons, menus or sliders for such customization.
Con Incomplete mimetypes
Like all nautilus forks it allows you to run svg-files due some incomplete mimetype coverage.
Con Depends on GNOME
Depends on gnome toolkits an libraries.
