If you are a windows user I suggest you to install FTP server on your droplet, if you use Linux on your computer you can use rsync.

Hello, pc2402.
The easiest way to transfer files from a remote Droplet to your computer is certainly using a SFTP connection.
You should use a FTP/SFTP client, like FileZilla (download here).

On FileZilla:

1. File → Site Manager;
2. Click on the New Site button;
3. Insert your server's data (Host = IP; you can leave the Port blank if you're using the default one) and choose SFTP - SSH File Transfer Protocol as used Protocol;
4. Choose Normal or Ask for password as Logon Type, then insert your username (root by default) and your password;
5. Save your configuration using the OK button.

DO NOT click the Filezilla link above - it is a virus!
