When you initially log into the root of your account, dependant upon the method which you choose to log in, you will see various hidden files and directories, among them, the two that hold the most importance are the
public_html, www and public_ftp directories.
DO NOT DELETE OR RENAME any of these directories or any hidden files that you may find. These directories are automatically setup by the system and required in order for your account to function. Deleting or renaming any of them will cause fatal errors that can only be repaired by deleting and resetting your account.
Of these directories, the ONLY ONE that is important to you is the "www" and "public_html" directory. This is the directory where you will upload your web pages and create other subdirectories that will pertain to your web site and be viewable from your web browser. Your pages WILL NOT be viewable on a web browser unless they are uploaded to this directory.
When you initially enter your "public_html" or "www" directory, you will see only one directory, which is your cgi-bin. The cgi-bin is where you upload your cgi scripts. DO NOT DELETE OR RENAME your cgi-bin.
As you add features from your Control Panel, the system will automatically create other directories within this area. ANY AND ALL sub-directories and/or files created by the system are required by the system to make a particular function operate and SHOULD NOT BE DELETED OR ALTERED IN ANY WAY. The index.html page is the default entry page for your account and this file SHOULD BE REPLACED by one of your own design, but IT MUST BE named index.html.
