If your are using a Linux or FreeBSD operating system on your local computer and have access to server shell, use the 'scp' command to copy files and directories to the server: scp your_file_name login@remoteserver.com:path to copy files, and scp –r your_directory_name login@remoteserver.com:path to copy entire directories.

After publishing, you will be able to work with files and directories on your account using SSH terminal web application integrated in your Plesk control panel (domain name > SSH Terminal).
