Symbolic links, how can personal folders move-point to another drive

Hi friends!
My question is about symbolic links (janction)
One from the reasons to use them is when you are out of space, so you can move folders with a lot of data
to another drive e.g music, videos etc... eg. mklink /j "C:\Users\Name\My music D:\Music, so that personal
folders point to a large drive

My problem is that when I try to do it I get the message "Cannot create a folder that already exist" ("My Music" in C:\)
Now, if I'll name it different is ok. but it is not anymore recognize from programs so is not useful because if I've
manually to store my data in the second drive I'll not get the benefits of symlinks.

I tried many ways... bringing a lot of mess in my system like to move the protected 'desktop.ini' file from "My Music" to
the new link and then delete the original but after I could not anymore open explorer only from the "Computer" shortcut in the
Start menu...

Anyway many words will make you tired... The question is :
Which is the right way to do it? Can someone discribe it? I'm sure there is a right way

Thanks a lot (sorry for my English)

I'm sorry, I just saw how many tutorials there are about my question.
Of course any idea is welcome

Hello essenbe
I thought this is the easiest way to do it after I've been looking to all the tutorials and threads... With your video also I'm now sure to follow this practice.
Now I've to reinstal 2 systems... because of the mess... I brought with my complicate ideas...
A small or big price to pay for acting before thinking and learning...
I thank you and mark the thread as solved.
