1. I think the subject of moving the Documents and Settings folder is partially alluded to in the article [Q818134], and it's internal links. Otherwise, you can review and perhaps use the suggestions in the article, "Cannot Move or Rename the Documents and Settings Folder (Q236621)" which Microsoft does not support and is also written for W2K, but is assumed to function appropriately in WinXP.
Documents and Settings -- contains a subfolder for each user profile (each user who has logged on to the computer or who has logged on to a network domain through the computer). Windows XP may create multiple profiles for one person if that person logs on in different ways. For example, you might have one folder for when you are logged on to the domain and another folder for when you are not logged on to the domain. Within each profile subfolder in the Documents and Settings folder, Windows XPcreates three folders:
My Documents: This folder is a convenient place to store documents, spreadsheets, and other files you want to access quickly.
My Pictures: This subfolder of My Documents has special capabilities for handling picture files.
My Music: This subfolder of My Documents has special capabilities for handling music files.
