File transfer programs are used to upload and download files across the Internet and local networks using FTP, or File Transfer Protocol. FTP is a special language used by computers to transmit files, and programs that use FTP are called "FTP Programs" or simply "file transfer programs."
File transfer programs come in many different types, and they exist for virtually all types of computing devices, including computers, tablets and mobile phones. File transfer programs can send files through both unsecured and secured channels. Uploading or downloading files securely is advised when using a file transfer program because other people can monitor and intercept unsecured connections, leading to possible data loss.
