DigitalOcean don't have any control panel to access or edit the files and FTP is not enabled on their VPS. They recommend to use SFTP and generate a security key for that but when I type 'ssh-keygen -t rsa' on Windows10 command prompt it says 'ssh-keygen is not recognized as an internal or external command'.
I am not a programmer and don't want to learn programming just to use their service. I had many web sites with different hosting companies and there always were a control panel or easy access to the files. Why do DigitalOcean make it so complicated? Is there a easier way to access the files?
