I just finished putting my first pc together and realized that none of the programs on my old hard drive opened since I installed Windows 10 on a 250 gb SSD. The old program file paths being non-existent now, it me took me some time to realize that and changing registry addresses and file paths was way over my head, and a risky and tedious option to top it off, so I decided to test launching something, Illustrator, by "reinstalling" it on my hdd and sure enough it worked. My concern here is that the deleted files from the hard disk end up in precious memory space on my SSD and I am worried that it might eat through memory space, even though they get deleted. Can somebody please tell me whether this is the case or not, and how to fix it. I can simply reinstall everything without deleting first, but I'll just bloat my HDD and I don't know how that affects load times and what not. Your responses will be greatly appreciated.
