I'm changing computers from an older machine to a new one and I want to copy the old syntax colors that I used in PHPed to the new machine. Where and what are the files that I need to copy in order to get the colors to the be same as well as the syntax formatting? The two versions of PHPed are exactly the same-- I'll be using the same installation file, so basically I just want to move it from my old machine to my new one.

That information is stored in the hl.cfg file, which, on XP, at least, is inside the phped folder, which is usually in C:\Program Files\nusphere\. For Vista, see this thread:

You'll probably want to grab some of the other config files while you're at it, as well as your templates folder. You may want to consider, too, moving over relevant registry settings.
