Using Copywhiz, you can keep your source and destination files in sync.

If a file is removed from the source folder, it will be deleted from the destination folder as well. This feature is a blend to the existing 'Automatically identify and paste only new and modified files' feature. You have to copy only recently modified files and delete a file from the destination if deleted from the source.

This feature will let you keep the same set of files in multiple folders.

If you have selected files in Copywhiz using the File Explorer (Windows Explorer), then go to the destination folder. Right-click inside the folder, choose Copywhiz → Paste Advanced to open the Copywhiz window and click on the 'Advanced Settings' button as shown in the picture below.
