copy folders to the root of the disk with EMCOPY

hello everyone

i have a problem with emcopy.exe tool .....i'm trying to copy "testfolder" to  disk G: ,

and by this syntax only the contents of the folder are copied to the disk .. and not the entire folder

emcopy.exe e:\testfolder  g:\    /o /a /stream /s /c /r:1 /th 64 /sdd /log+:c:\temp\emcopy.log

what did I do wrong with the command syntax?

Thank you
