Add this to your toolbar (See Button .dcf Files in How to use buttons and scripts from this forum):

Go to the folder where you want to create the Covers folder:

Click the button:

Script code for reference:

function OnClick(clickData)
{
	var cmd = clickData.func.command;
	cmd.ClearFiles();
	cmd.deselect = false;

	var folderName = clickData.func.sourcetab.path.filepart;

	var matches = folderName.match(/^[^.]+/);
	DOpus.Output(matches.length);
	if (matches.length != 1) { return; }

	var newName = matches[0] + ' Covers';
	cmd.RunCommand('CreateFolder NAME="' + newName + '"');
}
