(at least without a lot of hacking which is beyond what we get into here.)
2. I strongly suggest you don't do this. HDDs are far slower than your SSD and at 120GB that's more than ample for say the Windows 10 OS. Why?
Over the past year I installed W10 to many 120GB SSDs and after the install about 99GB was free so the only trouble was when users would install apps on drive C instead of another drive.
3. It would do nothing but copy. If you had asked "If I just MOVE" then my answer is you just wiped out your installed OS.
--> My advice is to uninstall what you installed on C and then reinstall those apps and watch for where it asks you where to install them.
First off, I am extremely inexperienced with computers. Just wanted to get that out of the way.
So, I recently had a new gaming computer built for me. My computer has 1 SSD (120 GB) and 1 HDD (1 TB), and all the system files, OS, etc. are on my SSD (doesn't leave that much space for games). If possible, I would like to free up space on my SSD, and move all the system files to my HDD which has much more storage space.
So my questions are:
1. How do I move all system files to my HDD?
2. How do I make my HDD my default drive, so that all future system updates are installed there.
3. If I just copy and paste all files over to my secondary drive, what would that do? would it mess up my computer?
