Currently I keep the trainers I use stored together in a folder on the same hard drive which also stores the bulk of my games. I am in the process of building a new rig and that hard drive will be "transplanted" into it within the next few days.

My question is:
I know the trainers have some type of key or copy-protection built-in that registers them, will they be okay being just uprooted into a completely new PC? Or do I need to delete the folder and just re-download them as I need them so they get properly registered to the new rig?

Thank you in advance for any insight on what the proper procedure is for this situation.
