when you are downloading from a link, instead of just left clicking it, right click and select: "save target as" this is going to let you select what part of your computer you would like to save to. so if you pick drive D, it will automatically default to that drive for future downloads. as far as p2p programs and such..simply change the user settings to choose a different directory for the program to save to. hope this helps out.
I have an 80GB hard drive (C=15GB, D=65GB).The problem is I keep getting "running out of space on local disk c" every time I download something. How can I fix it so I keep the recommended 250MB open on C and new stuff automatically downloads to D drive w/out re-partitioning?
