SFTP uses the Secure Shell (SSH) protocol, so if you are unable to SSH you probably won't be able to SFTP either. ```unix ssh your_username@hostname_or_ip_address ``` ### Start SFTP Session This uses the same syntax as SSH and opens a session in which you can transfer files. ```unix sftp your_username@hostname_or_ip_address ``` To list helpful commands: ```unix help ``` ### Transfer files and folders To download a file: ```unix get ``` To download a folder and its contents, use the "-r" flag (also works for uploading): ```unix get -r ``` To upload a file: ```unix put ``` ### Change folders To change the local folder: ```unix lcd ``` To change the remote folder: ```unix cd ```
