Well, what I do is move it to another hard drive on another machine via my home network, but even moving it to c:/Runtime would protect it from a reinstall, so long as you watch your directory path on the reinstall. But, you can split it up to separate CDs, it will be a little time-consuming though. It's always good to have a hard back-up anyway. :) Just create a Runtime folder on each CD, and select different sub-folders to put inside each one, spacing the amount of data as evenly as possible between them. You geometries folder is probably the big one. See if you can fit that on one disk, just remember to keep your paths intact so copying them back is simple! Tilandra
