I’m new in Visual Basic, and I’m trying to create a program that will copy selected files to a specific destination. I have attached my form and a screenshot with some details so that you can have a good idea of what I'm doing, I hope you can you can help me on this.
Thanks in advance.

You haven't really specified what problem you are facing so it is difficult to offer any suggestions. For copying files in VB, you can use the FileCopy function.

FileCopy <SourcePath> <DestinationPath>

You cannot use FileCopy on a file that is already opened
