Multicolumn Listbox

[PReitano]

Enclosed is a program that was developed by one member of the NI community.
Great program using a multicolumn listbox as a file explorer window. 
However I like to modify this program to included a 2nd multicolumn listbox and transfer a group of selected elements to the 2nd multicolumn listbox.
I was capable of transfering one item to the 2nd box however I am having difficulties in coming up with a what to transfer a selected group.

Hello,

I'm not sure I understood what you'd like to do...

Do you mean you want a selected group of file to be transfered to the second listbox when you clic the "transfert" button ?

[PReitano]

Yes, that is correct.
Sorry for the lack of clarity.

See if this will do what you want.

Thanks for your help, however I forgot to specify that the contents in the 2nd listbox does not get deleted.
Each time I transfer 1 or more items it should append.
