Grouping folders by tags

[blazewardog]

Does anyone know how to do this in Windows 7 x64? what i mean is

(click to show/hide)

I want to use category or some other tag on my anime folders and then group by the tag but I can't seem to be able to set the metadata on folders only certain types of files.
Does anyone have a clue how to do this? I can only seem to find this for windows XP and considering if you right click there is a group by option I would assume 7 still has this.

Everything I've read says that you can't tag folders in Vista (and Win 7 as of now). You might want to look into using an alternative file manager to explorer.

Or you could use Libraries for that purpose.

Why not use XBMC?
