Documents, Pictures, and Music Folder locations

I have an XP Pro machine, (and others) with separate partitions, and relocated personal folders. For example, D:\My Documents. Obviously, my My Pictures, and My Music are subfolders of My Documents on the XP machine. When installing the portableapps platform on my data drive [D:], which has the path d:\portableapps\ , I told it the location of my portableapps folder is D: So far, so good. However, it has not recognized the My Documents folder, and created just D:\Documents, which is the target of the "Documents" icon on the portableapps menu. I would like to "tell" the platform the path to the "My Document" folder that existed prior to the portableapps install, so clicking on "Documents" would go to "D:\My Documents", Pictures, would go to "D:\My Documents\My Pictures", etc... I have looked in various ini files, and have not found a way to do this. Is there a way?

Thanks in advance, and thank you for the otherwise fine work.
