 3. Level 3 directories **el1/** and **el2/**: indicate directories for files of different encryption levels (els).
    - **el1**: directory for the data that can be accessed once the device starts. This directory contains device-focused files.
    - **el2**: directory for the data that can be accessed only after at lease one successful unlocking operation (by PIN, fingerprint, or facial authentication, or password-free sign-in) upon the start of the device. This directory contains user-focused files.<br>
-   Unless otherwise required, application data is placed in the **el2** directory for security purposes. However, the data that needs to be accessed before the screen is unlocked (such as the clock, alarm, and wallpaper data) can be placed in the **el1** directory. For details about how to switch to and modify the **el** directories, see [Obtaining and Modifying el Directories](../application-models/application-context-stage.md#obtaining-and-modifying-encryption-areas).

    The application's global data is stored in the **files**, **cache**, **preferences**, **temp**, and **distributedfiles** folders in **base**. You can use **ApplicationContext** to obtain the application file paths of these folders.
 
-   You can use **UIAbilityContext**, **AbilityStageContext**, and **ExtensionContext** to obtain application file paths related to the OpenHarmoy Ability Package (HAP). When the HAP is uninstalled, the files stored in these directories are automatically deleted, without affecting the files in app-level directories. An application in the development state contains one or more HAPs. For details, see [Application Package Structure in Stage Mode](../quick-start/application-package-structure-stage.md).
