This understanding also allows you to grasp how WordPress functions internally and which files are crucial for backup.
How to Access Your WordPress Files and Directories
Your WordPress files are stored on your web hosting server. You can access them using an FTP client or the File Manager tool in your WordPress hosting control panel.
An FTP client is a specialized application for connecting to your server. Check our guide on using FTP to upload WordPress files for comprehensive instructions.
For many users, a simpler option is the File Manager tool, which is included in most WordPress hosting control panels.
After connecting, you will find your WordPress files located in the /public_html/ or /www/ directory.
This section presents a typical file and directory structure for WordPress.
Within this main directory, you’ll find the essential WordPress files and folders that power your website. It’s important to avoid making direct edits to these files, except in rare cases such as .htaccess and wp-config.php.
Below is a comprehensive list of the fundamental WordPress files and directories. In this list, [dir] signifies a directory, which is essentially another term for a folder.
- wp-admin [dir]
- wp-content [dir]
- wp-includes [dir]
- index.php
- license.txt
- readme.html
- wp-activate.php
- wp-blog-header.php
- wp-comments-post.php
- wp-config-sample.php
- wp-cron.php
- wp-links-opml.php
- wp-load.php
- wp-login.php
- wp-mail.php
- wp-settings.php
- wp-signup.php
- wp-trackback.php
- xmlrpc.php
Please note that the list above does not include .htaccess and wp-config.php files. These files are generated after the completion of the main WordPress installation.
Essential WordPress Configuration Files
The primary WordPress directory contains essential configuration files.
These files store crucial settings tailored to your specific website.
- .htaccess – This file configures server settings. WordPress utilizes it to manage permalinks and redirects. Keep in mind that the .htaccess file is applicable only to Apache web servers; if your hosting provider uses a different server type, such as Nginx, this file will not be utilized.
- wp-config.php – This file instructs WordPress on how to connect to your database and establishes global settings for your site. For enhanced security, you can relocate this file one level above your public root directory, and WordPress will still be able to locate it.
- index.php – This file serves as the entry point. It initiates the loading process of the WordPress framework to render your website when a visitor arrives.
You may occasionally need to modify wp-config.php or .htaccess. Exercise extreme caution when editing these two files. A minor error can render your site inaccessible, so always create backup copies on your computer before making any modifications.
If the .htaccess file is not visible in your root directory, refer to our guide on why the .htaccess file might be hidden.
Depending on your website’s configuration, you may find these files in your root directory:
- robots.txt – this file provides guidelines for search engine crawlers. Check out our guide on optimizing the WordPress robots.txt file for better SEO.
- favicon.ico – a favicon file is occasionally created by WordPress hosting providers.
- llms.txt – this file offers instructions for AI crawlers to enhance Generative Engine Optimization. You can generate it using the All in One SEO plugin for WordPress.
Exploring the wp-content Folder
WordPress saves all user-uploaded content, including uploads, plugins, and themes, in the wp-content directory.
Although this is the folder you will use most frequently, exercise caution. Making direct changes to files here without proper knowledge can lead to errors or even break your website.
Let’s take a closer look at the wp-content directory to see how it operates.
While the contents may vary from one website to another, all WordPress sites will include the following:
- [dir] themes
- [dir] plugins
- [dir] uploads
- index.php
Themes Directory (/wp-content/themes/)
The theme files for WordPress are located in this directory. We advise against modifying theme files directly, as updates to the theme may overwrite your changes.
For any customizations to your theme, we strongly recommend creating a child theme.
Here’s an alternative tip for beginners 💡: Most users will find it much simpler to use SeedProd, a drag-and-drop theme builder, rather than editing code manually.
Plugins Directory (/wp-content/plugins/)
All the WordPress plugins you install on your site are stored in this directory. Avoid editing plugin files directly unless you have created a custom plugin for your own use.
Many tutorials provide code snippets to incorporate into your site. The simplest and safest method to add this custom code is by using a code snippets plugin.
We suggest using a plugin like WPCode, as it helps prevent errors that could potentially break your site when modifying files such as functions.php.
This plugin also helps keep your code snippets organized and separate from your theme. We utilize WPCode to manage code snippets on our own websites.
For more information, check out our comprehensive WPCode review or follow our guide on adding custom code snippets in WordPress for detailed instructions.
Uploads Directory (/wp-content/uploads/)
WordPress saves all your images and media files in the /wp-content/uploads/ directory. By default, these uploads are organized into subdirectories by year and month.
⚠️Important: When creating a backup of your WordPress site, be sure to include the uploads directory. While you can re-download the WordPress core, themes, and plugins, this directory contains your unique content. Losing it can make restoration without a backup very challenging.
Additional Directories in wp-content
You may notice several other directories in your wp-content folder:
- languages – This is where WordPress keeps language files for non-English versions of the site.
- upgrade – A temporary folder created by WordPress during upgrades to newer versions.
Many WordPress plugins also generate their own directories within wp-content. For instance, some plugins create folders in /wp-content/uploads/ to store user-generated files.
This demo site includes folders created by the Smash Balloon, WooCommerce, SeedProd, and WPForms plugins.
Some of these directories may contain crucial files, so we recommend creating backups as a precautionary measure.
Other directories, such as those generated by caching plugins like WP Rocket, may hold data that can be safely removed.
Exploring the wp-admin Folder
Thewp-adminfolder houses all the necessary files to operate your WordPress admin dashboard. This is the backend area where you create posts, modify themes, install plugins, and manage your website.
It contains files such asadmin.php,index.php, and directories for JavaScript, CSS, and images utilized in the dashboard interface. When you log into WordPress, all visible elements are loaded from this folder.
Unless you are a developer customizing the admin area, there is no need to access or modify anything within thewp-admin. These files are vital for your site’s functionality. Altering or removing even a single file can disrupt your website.
If your admin panel fails to load, it is safer to reinstall WordPress or restore from a backup rather than attempting to fix anything within this folder manually.
Exploring the wp-includes Folder
Thewp-includesThe folder serves as the core engine of WordPress, housing essential code that enables its functionality, including the scripts, functions, and classes that drive themes, plugins, and various features.
This folder contains numerous files, such as functions.php, class-wp-query.php, along with directories like js and fonts. These files manage tasks such as loading posts, displaying widgets, and facilitating the interaction between your theme and WordPress.
It is crucial to avoid editing any files within the wp-includes folder. These are vital core files managed by WordPress, and any modifications made here will be lost during updates. A single error could potentially disrupt your entire site.
For customizing functionality, it is advisable to utilize plugins, hooks, or custom code snippets using a tool like WPCode. This approach ensures your changes remain intact even after WordPress updates.
Common Questions About WordPress File and Directory Structure
Is it safe to remove core WordPress files?
No, you should never remove core WordPress files located in the wp-admin or wp-includesBe cautious with folders; deleting them can disrupt your website’s functionality. If you suspect a file is damaged, replace it with a new version from the official WordPress download.
Is it safe to edit the functions.php file of my theme directly?
While it is possible to edit the functions.php file directly, it is not advisable. A small error could lead to the ‘white screen of death,’ and any modifications will be lost when you update your theme. It is safer to use a child theme or a code snippets plugin like WPCode.
What are file permissions, and why are they important?
File permissions determine who can read, write, and execute files on your server. Incorrect permissions can pose a security risk. Typically, directories should have permissions set to 755, while files should be set to 644.
