Changing path files for My Music and similar?

[DarkShadow]

As above, I'm wanting to partition my music so if I do re-format, I wouldn't have to replace my music.

Now how would I go about changing the path files of My Music, My Pictures and similar?

Thanks

It's funny how the simplest of things boggle some of us
