Examples
an example FTP Script to retrieve files in binary and then ascii mode:

[User_id]
[ftp_password]
binary
get /usr/file1.exe
get file2.html
mget *.jpeg
ascii
mget *.txt
quit

To run the above script:
FTP -s:GetFiles.ftp [hostname]
This will connect as the user:User_id with password:ftp_password

An FTP Script to publish files in binary mode:

::PutFiles.ftp

[User_id]
[ftp_password]
binary
mput *.html
cd images
mput *.gif
quit

To run the above script:
FTP -s:PutFiles.ftp [hostname]
This will connect as the user:User_id with password:ftp_password


Using the Windows GUI for FTP
Windows Explorer (not Internet Explorer) also has a built in FTP client.
Type in the address bar:

ftp://username@ftpserver.address.com

you will be prompted for the password.
You can also use

ftp://username:password@ftpserver.address.com

This is not recommended as anyone can read the password.

Secure FTP
Standard FTP does not encrypt passwords – they are sent across the network in plain text. A more secure method is to use SecureFTP (SFTP) or SecureCopy (SCP) Freeware clients are available such as WinSCP.
