I don't have many quilt related things on my computer. I keep pics of the quilts I have made on photobucket and a external hard drive. My patterns are in binders that I keep on a shelf. I have EQ5 loaded but I don't use it that much. I use graph paper and colored pencils more than EQ5.
I have a lot of embroidery designs stored on my computer but they don't take up that much space.
Just get an external hard drive and keep it near your computer and just plug it up when you want see your quilt related things.
