Application resources are defined in the project's **resources** directory, which is organized as follows:
- Level-1: base sub-directory, qualifiers sub-directories, and rawfile sub-directory
- Level-1: **base** sub-directory, qualifiers sub-directories, and **rawfile** sub-directory
- The base sub-directory is a default directory. If no qualifiers sub-directories in the resources directory of the application match the device status, the resource file in the base sub-directory will be automatically referenced.
- The **base** sub-directory is a default directory. If no qualifiers sub-directories in the **resources** directory of the application match the device status, the resource file in the **base** sub-directory will be automatically referenced.
- You need to create qualifiers sub-directories on your own. The name of a qualifiers sub-directory consists of one or more qualifiers that represent the application scenarios or device characteristics, covering the mobile country code (MCC), mobile network code (MNC), language, script, country or region, screen orientation, device type, color mode, and screen density. The qualifiers are separated using underscores (_) or hyphens (-).

## Referencing Resources
## Referencing Resources
To reference an application resource in a project, use the ```"$r('app.type.name')"``` format. **app** indicates the resource defined in the resources directory of the application. **type** indicates the resource type (or the location where the resource is stored). The value can be color, float, string, plural, or media. **name** indicates the resource name, which you set when defining the resource.
To reference an application resource in a project, use the `"$r('app.type.name')"` format. **app** indicates the resource defined in the **resources** directory of the application. **type** indicates the resource type (or the location where the resource is stored). The value can be **color**, **float**, **string**, **plural**, or **media**. **name** indicates the resource name, which you set when defining the resource.
When referencing resources in the **rawfile** sub-directory, use the `"$rawfile('filename')"` format. Currently, **$rawfile** allows only the **\<Image>** component to reference image resources. **filename** indicates the relative path of a file in the **rawfile** directory, and the file name must contain the file name extension. Note that the relative path cannot start with a slash (/).

In the format, **filename** indicates the relative path of a file in the **rawfile** directory, and the file name must contain the file name extension. Note that the relative path cannot start with a slash (/).
> Resource descriptors accept only strings, such as `'app.type.name'`, and cannot be combined.
