Please forgive me if this question has been asked before, but I cannot find anything on this subject. I now have Logos 4, but I am getting an error message stating that I am out of hard drive space. This is strange because I have a 400 gig hard drive. I have repartition the drive so I could have "two hard drives." I use my "c drive" for the OS and computer programs. I use my "d drive" to store all of my data files. Before installing Logos 4, I had just under 5 gig. Is Logos 4 that big of a program? I am taking a guess that it is my books that is taking up sooooooo much space. Is there a way to move the books to my data drive? thanks
