Well, I don't know, I guess we need to see your code.  It'not a bug and it works fine for me.

SysMoveFile() simply invokes a single Windows API.  It is the Windows API that is returning the error code.

The Windows doc says the second argument is:

The new name for the file or directory. The new name must not already exist. A new file may be on a different file system or drive. A new directory must be on the same drive.
