You have already taken steps to mask where your installation files are by renaming the system directory. Taking this one step further, you can change where you log into the control panel, so that you do not reveal your installation directory when you give others access to the control panel.
1. Copy the file
/system/index.php
and rename the copy toadmin.php.
2. Move the copy to the root of the ExpressionEngine website.
3. Next, using a text editor such as Wordpad, open
admin.php
and search for the line$system_path = ""
;. Inside the double quotes, type./system
(replacingsystem
with the name you chose for your system directory). Then save and close the file.4. Now try logging in to the control panel by pointing a browser at
http://localhost/admin.php
and using the username and password chosen during installation.
