restore rekordox collection

Hi,

My main question: Could I change the place where the "system or rekordbox" copy the musics from the backup library during the restore library procedure?  
I made backup library whit musics, then I wanted to restore that. It was more or less successful, but I don't have enough space on that hard disk (I could use a most of musics) I have enough empty space on other hard disk, furthermore I wanted to restore my collection on this bigger hard disk, but I didn't find opportunity for choice... I hope is it clear...
So, could someone help me? :)
