"What I want to do is when (or if) I get a new PC, copy my N3V games folder and put it on a removeable hard drive. So, if I do that, will I still have all of my DLS downloads and 3rd party downloads?" Hi Jacob, you don't necessarily have to get a new computer all you need is an extra hard drive. Most modern computers will run multiple hard drives and already have the hardware fitted to do that (power cables, shelves). Depending on its capacity and speed a reasonable hard drive can cost as little as $70 - look on the net there are plenty available. Also, hard drives are very easy to fit, it is just a matter of attaching the four screws, power and SATA cables. I am running three internal hard drives and an external drive (which is also another option for you). Have a look at those options, as they are much cheaper than buying a new computer. Also, you will not need to worry about transferring all of your content to a new computer - which can be a very trying experience.
