The other option that I use is Symbolic links.  What this does is point a folder to another folder.  This is very useful for Poser in that Poser creates a folder called Purchases inside the Poser 14 Content.  this is where Poser will download content to.  While nice in that fact it keeps it together it makes it hard to manage if you have Poser 11, 12, 13 and 14 since they all the same Purchase folder and it is separate from the others.  So I have made a Symbolic link to a single folder and placed the link inside each content folder so the program sees it as its own but they all share the same location so I don't down load the same content several times.
