Anyone still using FTP should read this and switch to SFTP. Steven Frank is co-founder of Panic, which puts out the excellent Transmit file transfer application.
There’s a much bigger difference between FTP and SFTP than just the letter S (and the meaning behind it).
This is advice I thoroughly agree with, for whatever that’s worth. I’m almost at the point where I’d pay extra to find a web host that doesn’t support FTP.
