I have a laptop and I'm running Windows 7. I recently downloaded AutoCAD and some other CAD software and I needed extra storage space on my laptop, so I bought an external hard drive. I was wondering if there was any way I could reinstall any programs onto the external HD to clear up some space in my internal HD. If not, I can always just use my external HD as a backup, which I was planning to do anyway. (The external HD I bought is 1 TB, just throwing that out there.) Thanks!
