Step 4: Create Config File
The fourth step creates your configuration file. The config.php file is the only file in Form Tools that stores custom data. It's not included in the original installation script or in upgrade packages so it will never be overwritten.
This step attempts to create the file automatically. If it cannot, you will need to manually create the file by creating it locally in notepad / textedit and FTPing it to your server.
The config.php file is located in the /global folder.
