How to Edit file in the cPanel File Manager?

Updated: 28 September 2026 · Applies to: cPanel & WHM 138 (Jupiter theme)

cPanel's File Manager includes a text editor, so you can change HTML, PHP, CSS or configuration files without downloading them.

Steps

1. Log in to cPanel (for example at https://yourdomain.com:2083, or from the Ucartz client area).
2. Open Files › File Manager and go to the folder with the file.
3. Right-click the file and choose Edit, or select it and click Edit in the toolbar.
4. If a character encoding dialog appears, keep utf-8 and click Edit.
5. Make your changes and click Save Changes. Close the editor tab when you are done.

Tip: Before editing an important file, right-click it and choose Copy to keep a spare copy such as config.php.bak. For hidden files like .htaccess, first enable Settings › Show Hidden Files (dotfiles).
