A graphical drag and drop interface for Rename, Move and Copy files. This is one of those tools that probably makes sense if you already know how to use it but for the rest of us looks daunting. It is one of those MC features that really has a "designed by an engineer" feel. Sometimes I and I'm guessing others just want to put files from here to there without reading a wiki.
I think you have answered your own question.
https://en.wikipedia.org/wiki/File_Explorer
"Drive & Devices > Explorer" is a powerful tool that provide "Windows Explorer" like functionality, while maintaining the MC Library records of where media files are. It has the basic functionality required of Adding, Deleting, and Renaming files and directories. Drag & Drop work. It doesn't use tags to move or rename files, and I suspect that any graphical Drag & Drop tool that allowed using tags would be as complicated, or more so, than the existing RM&CF function. It can act on only files in the Library, or on all files in a directory. Of course, all the same issues that come up with the RM&CF function moving or not moving ancillary files would also come up with a graphical tool, including the MC Explorer tool.
So use "Drive & Devices > Explorer" instead. Use the checkboxes at the top to change the way it works, particularly so you only operate on files in the MC Library, or all files in a folder.
Frankly though, while the RM&CF function has some quirks and requires a bit of knowledge to get the most out of it, it isn't that hard to use, it shows you what it is going to do before doing it, and if you can't understand it then you probably aren't getting the most out of MC Views, Searches, and a whole lot more MC functionality.
Won't read the Wiki to learn how to use the function? Who is that hurting?
Find the Wiki hard to understand? Well, why don't you learn it and write a better Wiki? Or improve the existing one?
BTW, I learned how to use the RM&CF function by... using it. Then reading the Wiki. Then using it. Then reading the Wiki again. It really isn't that hard. Set up a test Library, copy some files into it, and practice.
Or just use Windows Explorer and let MC find the files again after you have moved them. But get your settings right for that first.
