Hello,
my recovery d drive is almost full and I have used a recovery system to recover my photos. My C drive is almost full also. Keeps telling me not enough space.
You can start by deleting files you no longer need or use and unistalling programs you don't use. You can also archive files you never use by burning them to a CD or DVD or even storing them on a flash drive. You can also use CCleaner ( http://www.piriform.com/ccleaner ) to recover some space.
