Move won't do this when moving files to another drive. you'll have to copy the files to the new drive and then remove them from the old one.
xcopy c:\temp\*.* d:\temp\*.* /s /v /i /h /k /y copies the temp folder and its contents to the d: drive.
rd c:\temp /s /q removes the temp folder and all contents from the c: drive.
Be careful with the "rd" command. When used like this it will remove the c:\temp directory and all files/folders in it. For example, if you get careless and type "rd c:\ /s /q", you will erase everything on your C: drive.
