I just tried to copy my `Users` folder from partition `C` to partition `D` [using the method mentioned in this post](https://serverfault.com/questions/8187/whats-the-best-way-to-move-c-users-to-d-users-under-vista-w7).

Unfortunately I encountered two problems:

1. When using the command `robocopy c:\Users d:\Users /mir /xj /copyall`, robocopy says that it can't find the file `C:\Users\`, although it exists.
2. When using the command `robocopy x:\Users d:\Users /mir /xj /copyall`, robocopy says that it cannot find the path `d:\Users\Administrator\Application Data`, `error code <0x00000003>`.

I started the command line mode of my Windows 7 installation disk (repair mode).

Does anybody know what the reasons for these errors might be?
