Hi! I just bought my first custom computer through a local company and unfortunately I didn't do a lot of research or ask a lot of questions. My issue is with the memory. I got 4 TB's. I assumed that all four would be on the C drive for the least complicated way to access all my programs and photos/videos. Or at least 1 tb on the C and the rest on a separate drive, since I asked for a lot of back up to store my huge library of photos and videos. What I actually got was 225 gb on the C drive and 3.63 on the D drive. I'm just about done installing my programs and what I have left on my C drive for memory is 136 gigs. Obviously, my biggest mistake was assuming that these folks could read my mind. That being said, I'm wondering if what I have makes sense to keep or should I go with one one of my original plans? My concern is that the C drive is going to get all filled up in the next year or so. The other issue is that it's constantly defaulting to the C drive. The company rep that I'm dealing with said that it's better to put all my programs, or as many as I can, on the D drive, which will free up the C drive for faster processing. Is this true? If so, then I can try to keep as much as I can on the D Drive. Also, is there a way to set up the D drive as the default?
