Change default locations of Program Files and Documents and Settings

this is my first post and I would really appreciate some help with it.
The unnattended.txt can be modified to winnt.sis for an unattended installation of XP, to move the default location of the program files and the documents and settings to other partitions residing on the hard drive. For a normal XP 32 installation the winnit.sis (or unnattended.txt as it is renamed) and is placed in the I386 folder.

Here it is:

;SetupMgrTag

The bits in red worked for XP32 why do they no longer work in 64. Do I have to set up more changes for both Program file types, even if the programs failed to move to new locations why would Documents and settings.
