Duplicate folders in C:\Users\

My main documents, contacts, videos (...) folders are on a totally separate
drive, relocated using the Location tab on the folder Properties.

It has been working fine for a year or more, but suddenly I keep getting
duplicate folders in C:\Users\Nigel\

Any way to stop this?

On a similar subject, is there any way to stop programs from creating
sub-folders in MY documents folder?
