The best way would probably be to make a link after you move it. A lot of applications search for your profile folder under
C:\users and moving it somewhere without making an association to it will give you a headache. After moving it over to
U:\<username> create a directory symbolic link to it:
MKLINK /J C:\Users\ U:
copy profiles to u:
value for future profiles and corresponding ProfileImagePath values for each of your existing (and relocated) profiles.
or just add this to startup:
subst u: "C:\Documents and Settings" 🙂
links approach is good too. http://schinagl.priv.at/nt/hardlinkshellext/hardlinkshellext.html
this tool seems best in convenience to operate with them.
