Copy and Paste or Cut and Paste will work.. I use Tera Copy for large file transfers like that because it does a check to make sure the files are copied correctly..
GraveDiggers may be trying to free up HDD space but still be able to access his user folders as normal:
Move user folder locations to Secondary HDD:
Go to your User folder.
Right click your user folder you want to move (ex. the "My Pictures" folder).
Click "Properties."
Click the "Location" tab.
Change the destination to another location bu clicking "Move..." and selecting the destination (ex. "D:\Pictures").
Note 1: If there are two of the same folder in the User folder after the move (ie. My Documents "A" and My Documents "B") you should delete the empty one located on the C: drive. (May need to go into safe mode to delete it) Do not delete the other User folders, only duplicates that come up after the move within the User folder.
Note 2: If the folder already exists that you are linking it to you may want to merge the folders.
