What is an FTP?
An FTP, which stands for File Transfer Protocol, is a method for transferring files from
one computer to another.
How do we select this list of the best free FTP software?
Supports secure file transfer protocols: FTP isn’t secure. Among its many flaws, plain FTP
doesn’t encrypt the data you’re transferring. If your data is compromised en route to its
destination, your credentials (username and password) and your data can easily be
read.
SFTP (which stands for SHH File Transfer Protocol) is a popular secure alternative, but
there are many others.
There are a lot of FTP clients with a command-line interface, approachable and easier
to use.
