A. Use Windows File Explorer. Navigate to the folder where your .JCP files are (shown in the above post.)
Display file extensions and details for that folder.
Highlight the .JCP files you want to copy.
COPY the highlighted group to the Windows Clipboard using the CTRL + C keyboard combination.
Navigate to your Destination folder.
And PASTE the highlighted group to the Destination folder using the CTRL + V keyboard combination.
Alternately, you could open two instances of File Explorer (with your Datafolder1 folder in the first instance and your Destination folder in the second.)
And just Drag and Drop the highlighted group of .JCP files to the Destination folder.
