There are a couple of ways you can do this
Either, create a new library for the folder you want to save to. To do this, just right click a folder in Explorer and choose Include in Library > Create new Library
Or, load up explorer and browse to the "Computer" folder you want to use in the right hand panel. Then, on the left, right click "favourites" and click "Add current location to favourites". This will add a quick link to your "computer" folder on every browse box. This may be the easiest way to achieve what you are after.
