FTP
What is FTP?
FTP stands for File Transfer Protocol, and is a method of transferring
files across the internet. Chances are, you've used FTP without even
knowing it. If you've ever downloaded software to your computer or
uploaded pictures or web pages to an online service, you were most likely
using FTP. These are two of the most common uses for FTP. In the
Internet's early days, most of the data that travelled over the Internet
travelled by FTP.
You
may have noticed that most of the web sites you visit using your web
browser start with HTTP? Well, this stands for HyperText Transfer
Protocol, and is another common way for files to be transmitted across the
Internet. However, unlike HTTP, which was designed to send small files to
a screen for display as soon as they are recieved, FTP allows many files,
including very large ones, to be queued up and sent as a "group" or
"batch" and saved as they arrive, rather than displayed.
This makes FTP the ideal way to get files from your home computer to a
remote server -- they are automatically saved to the server's hard drive
as soon as they are received.
FTP
has many other benefits as well, such as the ability to know whether all
of the "batch" was delivered properly and the ability to resume sending
where it left of if a transmission is interrupted, and more importantly to
web site owners, the ability to view, rename and delete files and folders
on a remote server without having to download them first.
If you are trying to use FTP to build and maintain your web
site, then the FTP features available to you will depend on the FTP
software on your computer, as well as the FTP server software and
permissions of the server you are trying to communicate with.
How Do I Use FTP?
You can use FTP by using software that knows how to communicate using the
FTP protocol. There are 3 main types of FTP software you can use for
maintaining a web site:
1) Your web browser - Very few people know that every
time they use their web browser, they are using an FTP-capable program.
Most modern web-browsers have basic FTP support built in. For example,
using Internet Explorer and Microsoft Windows, you can type FTP://yourFTPusername:yourFTPpassword@yourwebsite.com/foldertouploadto
right into the address bar, and it will show you all the files that are
listed on your web site. (If you don't want your password to be displayed
in the address bar, you can just type FTP://yourFTPusername@yourwebsite.com/
foldertouploadto and it will ask you for your password). Once your browser
has connected via FTP and is displaying the files in your remote site, you
can just drag and drop (or cut and paste) files from your desktop to the
window and they will be uploaded to your site. This is a very easy and
little-known way to upload files to a web server. You can even bookmark
the address on your remote site for quick FTP access whenever you want to
connect to your site.
2) FTP software (or "client") - There are large number of
FTP programs that are available out there, ranging from free to shareware
to expensive commercial software. Two very popular and easy to use ones
that we have used and recommend are
WS_FTP and
CuteFTP. If you code your own web-pages using a text editor such as
notepad, or just want a lighter weight program to manage things on the
server without opening your whole page editing software, these programs
are an ideal choice. They are easy enough for inexperienced webmasters yet
powerful enough that you'd never need to use anything else.
3) Page Editing Software - Most web page editing/creation
software includes the built-in ability to upload, download and manage
files on a remote server using FTP. For example, I am currently using my
favorite page editing software,
Macromedia Dreamweaver MX to write this. When I am done editing, I
click a button and Dreamweaver automatically transfers the updated files
to the server. Two other popular page editing programs that include this
functionality are
Microsoft FrontPage 2002, and
Adobe GoLive 6.0. For me, having FTP integrated into the program I
also use to create and edit my web pages is the fastest and easiest
method.
What is Anonymous FTP?
Some web hosting services allow you to have what is called "anonymous
FTP". This is basically an "open" FTP account, allowing people to upload
files to the server without having to have their own username & password
(or without having to tell them yours!). Usually the username is just
"anonymous" and the password is a valid e-mail address. This type of
account is typically used by software archives that want to accept files
submitted by site visitors, but it is also used as an easier way to allow
people to send large files to you than by using e-mail attachments. As you
can probably guess, anonymous FTP accounts often end up being havens for
pirated or copyrighted material, and are sometimes more trouble for a
hosting company to police than they are worth. You will generally only
find anonymous FTP on higher end hosting packages or smaller hosts that
aren't big on security. For most people, anonymous FTP is not a necessary
feature.
What are multiple FTP accounts?
Some higher-end web hosting plans will allow you to create additional FTP
"accounts" or "users". Each account has its own unique username and
password. Typically, each account has its own folder on the server that it
has access to. Depending on how the web host has things setup, all FTP
accounts could have access to the same folder, only their own folder, or
you (from your main account) may be able to configure the access allowed
for each additional account.
Do I need FTP Access?
FTP hosting is a must for editing and uploading pages to your web site.
Many free hosts will not allow FTP and users must create pages directly
through an online site builder program or upload them through a web-based
file manager, which may only allow you to upload one file at a time. This
is a painfully slow process if you have more than 5 or so pages on your
site. Be sure that your web host offers FTP access to your site. It is
essential for making file/site uploading simple.
