Revolutionizing Data Management with HarmonyOS NEXT


After two weeks since the HDC 2024 event, discussions about HarmonyOS Next have cooled down. This article delves into an often-overlooked aspect of HarmonyOS NEXT: its significant changes in data management.

Enhanced Data Security and Control

HarmonyOS NEXT has revamped its file service framework, introducing a new distributed intelligent data infrastructure. This new data foundation makes cloud storage the central hub for HarmonyOS data management. This enhancement ensures data is more secure and controllable, while also improving the utilization of cloud storage on mobile devices.

Granular Data Access Control

To illustrate, consider a scenario where a user wants to share a photo on a social media platform like Xiaohongshu. Previously, the system would grant the app full read and write access, akin to handing over a master key. In HarmonyOS NEXT, the system restricts access to a single use basis. The app specifies which photo it needs, and the system’s photo picker retrieves it, adding a layer of security and privacy protection.

Unified Data Access Across Devices and Cloud

HarmonyOS NEXT integrates cloud storage into the system layer, merging local and cloud storage spaces. This unification allows for seamless data management and access, enhancing the efficiency of cloud storage utilization. Users can now access cloud-stored files as easily as local ones, eliminating the need to download files for sharing.

Optimized Device Storage Management

HarmonyOS NEXT introduces an automated system for managing device storage. By enabling “Optimize Device Storage,” the system intelligently manages storage based on factors like available space, usage habits, and device performance. This feature automatically moves rarely used files to the cloud when storage is low, akin to an automated storage organizer.

Streamlined Developer Experience

For developers, HarmonyOS NEXT simplifies the process of accessing and managing data. Apps can directly interface with the system’s file service framework, reducing the need for custom solutions. This integration not only saves development time but also enhances efficiency, with developers now able to focus on data processing rather than infrastructure setup.


HarmonyOS NEXT’s advancements in data management promise a more efficient, secure, and user-friendly experience. With its integrated approach to data handling, users and developers alike can expect a streamlined and powerful ecosystem when HarmonyOS Next is officially launched.
