Some FTP sites are open to anyone, others offer restricted access only.
All FTP sites require you to log on, but so-called 'Anonymous' sites don't specify a specific username and password, so anyone can use them.

Folders or directories
Most computer users tend to use talk about the 'folders' on their harddisks, while FTP programs usually describe them as 'directories'. But the terms folders or directories are pretty much interchangeable.
The Win32 Internet Extensions, or WinInet, provide access to common Internet protocols, including gopher, FTP, and HTTP. Using WinInet, you can write Internet client applications at a higher level of programming, without having to deal with WinSock, TCP/IP, or the details of specific Internet protocols. WinInet provides a consistent set of functions for all three protocols, with a familiar Win32 API interface. This consistency minimizes code changes you need to make if the underlying protocol changes (for example, from FTP to HTTP).
