So I've been trying to install the NMC small texture pack, and everytime I attepmt to I run into the same problem. It will be 3/4 of the way installed, then a pop-up will say I don't have enough disk space on the local disk. The NMC small texture pack is 878,714 KB, and I have 4.64 GBs of empty space. Halp.
