Use xcopy-command for entire folder

The project configuration file has post-build events. Those are xcopy commands copying files from certain subfolders in the solution folder to the output folders.

- [ ] Change the commands to copy the entire subfolders instead of using one command for each file.

Locate the project configuration file's post-build events and review the existing xcopy commands for the listed subfolders. Change the commands so each entire subfolder is copied, then verify that the output folders contain the expected folder contents after a build.
