Here's something you might want to know - if you "Save As" your fractals and w.i.p.'s, etc. as "fractals" (.ufr files), they are going to take up a gigantic chunck of your harddrive in time. They produce a file orders of magnitude larger than a .ucl parameter file. It IS nice that they open faster but, myself, I just save the "mega-layer fiascos" that way so they don't take 30 minutes to draw themselves. 99% of the time I use the "Save Parameters" (.upr files) option that gives a preview look at what the image/layer is and only costs a few kb of space. Makes backing up to CD's more efficient, too, as you can get more onto a disk. I suppose, if you had a DVD writer, those hold more info but you might end up with everything on one disc. If anything happens to that disc you're screwed. A real concern in light of the recent debunking of the false claim that CD's would last over 20 years. All the studies now show that you will be lucky if the CD is still readable after 2-5 years - and that's if you use higher quality discs. I back up EVERYTHING, par's, formulae, gradients monthly to new discs. This has proved invaluable when an image is "broken" by a new version of a .ucl. I've been able to recover by going back as far as 2003 to get the version of the ucl that worked for the image. Good luck! Rick
