Core Viewpoint - The article addresses common misconceptions regarding WeChat's storage space usage and clarifies how the app manages data to optimize user experience while protecting valuable data like chat history [1][3][5][7][11]. Group 1: Misconceptions about Storage - Forwarding the same file in WeChat does not result in duplicate storage due to the use of "hard link" technology, which ensures only one copy is stored [1]. - Deleting chat records does not occupy space as WeChat employs an "asynchronous deletion" mechanism to clear data in the background without interrupting user experience [3]. - Expired files do not occupy storage space, as they are either not downloaded locally or have been actively cleared [5]. Group 2: Notifications and User Experience - WeChat prompts users about low storage to prevent data corruption and loss of chat history, with notification thresholds set at 700MB for iOS and up to 1GB for Android [7]. - Disabling "auto-download" may improve storage for users on multiple devices but could lead to missing content in chat history [9]. Group 3: Installation and Necessary Files - The WeChat installation package has grown significantly over the years due to increased functionality, but ongoing optimizations have led to a decrease in package size in recent versions [11]. - "Necessary files" are essential for the app's operation and include code files, user configuration data, and frequently used features, with efforts ongoing to optimize their storage [13]. Group 4: Data Management and Optimization - Many features developed based on user needs do not necessarily increase storage usage, as data from features like mini-programs and Moments are cached and can be cleared without affecting functionality [15]. - Users with over 40GB of storage used for WeChat find that chat history accounts for an average of 70% of their storage usage [16]. - WeChat has implemented several optimizations to manage storage effectively, including tools for bulk cleaning of high-quality images, avoiding duplicate saves, and allowing file previews before downloads [18][20].
