## Obtaining the Sandbox Path
For the FA model, the sandbox path of a bundle can be obtained using the APIs in [Context](js-apis-inner-app-context.md). For the stage model, the sandbox path can be obtained using the property in [Context](js-apis-inner-application-uiAbilityContext-sys.md#abilitycontext). The following describes how to obtain the sandbox path.

**Example**
``` ts
// Stage model
import UIAbility from '@ohos.app.ability.UIAbility';
import window from '@ohos.window';
export default class EntryAbility extends UIAbility {
    onWindowStageCreate(windowStage: window.WindowStage) {
        let context = this.context;
        let pathDir = context.filesDir;
        console.info('sandbox path is ' + pathDir);
    }
}
```

<!--code_no_check_fa-->
``` ts
// FA model
import featureAbility from '@ohos.ability.featureAbility';
let context = featureAbility.getContext();
context.getFilesDir().then((data: string) => {
    let pathDir = data;
    console.info('sandbox path is ' + pathDir);
});
```
