Windows Mass Renamer

Hi, is there any program you know of that can do a 'mass rename' of of all the file paths on a hard drive? I installed Windows on a friend's hard drive, so it mapped as D: and so everything is under d:\

Is there a way I can change that so that when I reinstall the drive into her computer everything will be under C:? I don't think it's that important, it will boot from there anyway I would think, but most people generally prefer it to be under C:…

Thanks!

Right click My Computer, Manage, Disk Management, right click D: and click Change Drive Letter and Paths

OOh, I tried that on the box with both hd's in it… Didn't think of doing it once I reinstall the HD, haha. Sorry, I temporarily was an idiot >_<

Thanks, system
