Q. Is it possible to move User folder (in its entirety) from C to D ?

I know I can move Documents, Music, etc, but I want to move the entire folder…

Answer.

Too many unintended and disastrous consequences to move the User Account folder to another drive.  Instead, just move your active User folders from your User account to the other drive.  User Folders – Change Default Location

This keeps C smaller for imaging purposes, but built-in imaging will want to include the data partition since it now has System files. The solution is to use a more flexible imaging app like free and fully automated Macrium Reflect is a Free and Easy To Use Backup Utility which can also restore anywhere instead of the exact same position on disk as per Windows imaging.
