What does "This couldn't be put back, so it's been left on your drive untouched" mean?
Short answer: The item couldn't come back cleanly, so Storage Studio left it untouched on your drive — nothing deleted. Check free space and the original place, then retry.
Something stopped the item coming back to your Mac — not enough space, the drive dropping out, or something already in its place. Rather than leave a half-restored copy, Storage Studio left it exactly as it was on your drive. Nothing was deleted.
Check free space on your Mac, make sure nothing new sits in the original place, then try again.
