Some months back, I moved 'My Documents' to C:\Data. All was well. Now I have had to move it to D:\Data. All is well, my library goes to the right place, docs save there correctly etc. The issue is that Windows Explorer still thinks that there is a folder called 'My Documents' in C:\ but there isn't and never really has been - it was always just a link of some sort to C:\Data. Now I want to rename C:\Data but can't - from Explorer or from the cmd line (as me or as Admin) even though the cmd line sees the folder as 'Data'. Any suggestions on how to make the OS forget that C:\Data was ever associated with 'My Documents'?
