Editing Folders Options

yo

I am a music freak
I also like to have everything organized

So I put the folder view on details and arranged the folders to my likings

but after awhile the folders are moved again?

So I thought of adding like, # to the folders
ex:



See the columns? I want to add to each folder
#1
#2
ect

At least then I know which was the first and last

Came here cause Google brought me here
also I can't find out how to do it.
Right-Clicking Properties is no option.

Thanks
