So any applications/files I want to access through the SSD OS will have to be downloaded onto the SSD in order to be used on the SSD OS instead of accessing my HDD while using the SSD OS?
"files" that are on the HDD can be accessed. As said, it's sort of a pain to access them in their current locations.
Applications WILL need to be reinstalled. You can install them on either drive, but they do need that actual new installation.
The ideal way to proceed with a drive change like this is to copy anything from the old HDD you really want to keep off to some other drive.
Then wipe that drive completely. Start with a blank slate.
Then, copy some stuff back.
And applications really do want to be installed on the SSD. They will benefit from that speed increase. That's why you have the SSD.
Games, not so much. You can have them on the HDD.
