Nothing against wget, but rclone IMO is better because it can handle both downloading and uploading.

For HTTP and FTP directories (the majority of the open directories that are posted on this sub), you can use rclone rather than wget if you want to download the entire directory (or tree it, check its total size, etc.)

rclone lsd --http-url [DIRECTORY URL] :http: to list the root directories

rclone copy -P --http-url [DIRECTORY URL] :http: /path/to/local/folder to download the entire directory (and display progress) to your local machine.

You can also use rclone to grab from public Google Drive links, or even copy Drive to Drive!
