1. Putty - the original SSH client and server. It is basically a no-frills program. You can use addons to enhance it.

B. Built-in SFTP client. You can view the files on the server. If you right-click you can choose to edit the file in the editor of your choice!
C. Macros to record settings if you have to type many steps to take. The next time you need it just run the macro!
D. And many more features!
