File Transfer Protocol
-
FTP is one of the original methods of sending files over the Internet. It is very common and is often the default method provided by Web hosting companies. A problem with FTP is that it sends your password over the network in clear text. This means that anyone can intercept your login credentials and illegally access your server.
It is possible to secure regular FTP using SSL encryption, as you would to access a secure Web page. Check with your Internet Service Provider to determine if FTP over SSL is available.
Secure File Transfer Protocol
-
SFTP is a secure method of transferring files over untrusted networks. It is not directly related to regular FTP. Secure FTP transfers files using Secure Shell encryption, which protects your sensitive account information and data. It is available on any server that runs an SSH service. Check with your Web hosting company to determine if SFTP is supported.

Which to Choose
-
The difference between FTP and SFTP will not affect how you move files to your server. Both will allow you to transfer files to your server quickly.
Selecting which one to use will be determined by what is available and whether you need strong security. You will need client software that supports the protocol you choose.
