You can allow anonymous FTP access to visitors wishing to download or upload files to your web site as if you were running your own FTP server. You can enable (and disable) ANON FTP access within your Web Control Panel.

Anonymous FTP warnings:

Security
Anonymous FTP will grant any and all users the ability to access your "upload" directory, or any directory on your domain that has been set for "public" read/write permissions. Anonymous users will have access to upload or download files to and from your domain. You must set the appropriate permissions for your directories to restrict anonymous FTP access. This is needed to ensure that anonymous users will not be able to access any existing files or directories. You can inhibit access to specific files and directories on our UNIX servers using the File Manager by disabling public read and/or write access to the files or folders you don't want people to see.

Responsibility
As the account owner, you are responsible for any and all files that are stored on your domain. This would include files that were uploaded by you as well as by anonymous FTP users. With the use of anonymous FTP, your site is susceptible of becoming a "warez" site. Typically, these are sites that are used by "hackers" to trade (upload/download) illegally pirated copies of software programs with one another. As the account owner, the complete content of your account is your responsibility. If your site becomes a trading post for "warez" programs, you may face legal action that can be taken against you by the programmers/software companies of the copyrighted software.
