FTP

FTP stands for:

File Transfer Protocol

It's a protocol defining how files can be transferred between computers.

An FTP program is a program that uses this protocol to transfer files between computers.

The most common usage of FTP programs is to upload files from a local computer to a server.

FTP sites are also sometimes used for downloading large files.

My personal favorite and one of the most popular FTP programs is call WS_FTP, available at www.ipswitch.com It's shareware with a free watered-down copy that works fine.

The upload functionality of FTP programs is being bundled into HTML editors... like FrontPage's "publish" feature.
