## What Are Files?

Files (assets) are static resources used in CMS sites — images, CSS stylesheets, JavaScript scripts, HTML files, and ZIP archives. Files are hosted on a CDN server and publicly accessible at a permanent URL.

## Key Features

- **Supported types** — images (JPG, PNG, SVG, GIF), CSS, JavaScript, HTML, ZIP files
- **CDN hosting** — files are stored on Amazon S3 and served through CloudFront, ensuring fast loading
- **Permanent URL** — each file has a unique name and a permanent URL for embedding in pages and templates
- **Automatic type detection** — the system recognizes the file type based on its extension
- **Folders** — files can be organized in a hierarchical directory structure
- **ZIP import** — upload a ZIP archive and the system will automatically extract it and create files preserving the folder structure

## Using Files

After uploading a file, use its URL in templates, pages, or CSS styles:

```html
<!-- Image -->
<img src="FILE_URL" alt="Description">

<!-- CSS in template -->
<link rel="stylesheet" href="FILE_URL">

<!-- JavaScript -->
<script src="FILE_URL"></script>
```

## Organizing in Folders

Folders allow you to organize files by topic (e.g., `images/icons`, `css`, `js`). Folders can be nested — each folder has a unique name within its parent folder.
