How To Move C:Users On A Different Partition

Used to be a time when I kept my the WIndows and core apps n a C partition, and my large users files on a D partition. In that way

- the C was samll, easily imaged to a second drive, etc,

- all data file were on the D partition, easily backed up to another drive

These days, with super large drives, and Windows expecting files in C:Users, I found myself keeping everything on the same partition - make those images much bigger and longer to create (unless one uses image software that allow oyu to exlcude folders) Is thee a way to tell Windows to look elsewehre (ie on another partition) for the user files its typically expects to see under C:Users ??
