I want to create a button for copy all file form N:\MPEGAV here to the active current folder

Thanks dear lxp, I have create this code, is that OK? or is there any better way to do? I mean The Drive Letter N is my CD ROM, But That's not be always N in every PC, I can't find to pass the CD ROM path. Is there any way to Pass the CDROM Drive?
Copy "N:\MPEGAV\*" TO HERE
Thanks bytespiller, I had saw the post, on that post the problem is same but He have a Drive label which is useable for solve the problem but in my case the CD ROM Drive has no label, so I can't use the label as alias, so what can I do in that case?
Hmm you would probably need to use the scripting and enumerate all drives with FSUtil.Drives which then returns a collection of Drive objects. You could then iterate the collection and figure out which drive is an optical drive via Drive.type (which returns one of these strings: removable, fixed, remote, cdrom, ramdisk).
It would be prudent to detect if there are multiple optical drives and handle that (for example let the user select the target or at least show an informative messagebox about which one will be used).
You could probably use other information provided by the Drive object, such as filesys or avail or free so you could probably detect which one has a blank media in it too etc. Be creative and experiment 
TO shouldn't be there. HERE is enough on its own:
Copy "N:\MPEGAV\*" HERE
(Copy "N:\MPEGAV\*" TO {sourcepath} would do the same thing. But using HERE is better.)
