You should also make a backup copy of your Word Press core files, for future reference and upgrades.
Note: If you use an external editor such as a word-processor to create and edit files, this can corrupt the file you are editing.
Please note that there are no advanced editor features such as: search and replace, line numbers, syntax highlighting, or code completion.
To edit a file using the built-in Word Press plugin and theme editors, the permissions for that file must be set to writable (at least 604).
Before editing any of your Word Press files, be sure to do the following: Word Press contains two built-in editors that allow you to edit theme files directly from your browser.
They are called the theme editor and the plugin editor.
More information on editing themes is available at Theme Development and Using Themes.
