Nip, I am so addicted I bought a 500 GIG external HDD just to save my stuff to. I have a 160 gig HDD in the PC and I was running out of room so this is how I got around it. Buy another EHDD. Cheeki is just as obsessed, she bought a 640 GIG EHDD.
Bucket, 'tis easy, pet. Just put whole folders onto a CD and then when you want to use tube/s just put the CD into the slot and go from there. You don't have to take the tube or pic or folder OFF the disc. It keeps them forever and it is just a matter of using the disc.
I have about 200 CDs with my tubes and scraps etc, so if I need something i just search my discs [I have them named and dated with a small description of contents] till I find something that suits the project I am working on.
