how to transfer a file over the Internet
There are three ways to transfer files over the Internet.
Via EmailEmail programs have the ability to "attach a file" to a message, which means that any type of file (program, graphics, spreadsheet, etc.) can be transmitted along with the text. This is the simplest way to send a file via the Internet. Before you send the message, all you do is click the "attach" button and point to the name of the file(s) you want to send along. See UUcoding.
Via a Cloud ProviderVery often, a mail gateway is set up to limit the size of attachments, and email cannot be used. The alternative is a storage provider such as Dropbox or Box, which require that you open an account, upload the files and invite a recipient to download them. See Dropbox and Box.
Via FTP and the WebThe protocol on the Internet that was designed to handle file transfers is FTP (file transfer protocol). It supports large files and the full 8-bit byte structure. With a Web browser, you can download from an FTP site, but not upload. You would use the ftp:// prefix and address (URL), which includes the domain name and directories.
In order to upload to an FTP site, you generally need an ID and password. If you have such privilege, you can use a terminal program and type in the raw Unix commands, or use a graphical FTP program with menus and buttons. There are always shareware or freeware FTP programs available on the Web. See FTP.
