Most of my designs are saved on 3 1/2 inch disc and again saved on cd's and again on a USB stick.
The 3 1/2's were saved when I first started on my designs. I have hundreds and hundreds on old 3 1/2 disk.
My new computer did not come with the 3 1/2 drive so I had to buy an A drive with a USB connector, 20.00 bucks, just so I could pull off what I had on the 3 1/2's and put them on the updated USB stick.
I now have a separate 80 G, hard drive for all of my designs that my daughter bought me for my birthday. I update it about once a month in case my computer crashes.
