关于“微信占内存”，官方回应了

Core Insights - The article addresses common misconceptions regarding WeChat's storage space usage and clarifies how the app manages data to optimize user experience. Group 1: Misconceptions about Storage - Forwarding the same file multiple times does not result in duplicate storage due to the use of "hard link" technology, which retains only one copy of the file [2] - Deleting chat records does not occupy space as WeChat employs an "asynchronous deletion" mechanism to ensure a smooth user experience [3] - Expired files do not occupy storage space and cannot be recovered, as they are either not downloaded locally or have been actively cleared [4] Group 2: User Notifications and Settings - WeChat prompts users about insufficient storage to protect chat data, with a threshold set at 700MB for iOS and up to 1GB for Android, significantly reducing notification frequency [5] - Disabling "automatic download" may help with storage for users on multiple devices but could lead to missing files due to undownloaded content [6] Group 3: Application Size 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 for the latest Android version [7] - "Necessary files" are essential for app functionality and include code files, user configuration data, and frequently used features, with efforts ongoing to optimize their storage [8] Group 4: Storage Optimization Efforts - WeChat has implemented several optimizations to enhance storage management, including one-click cleaning of high-resolution images while retaining lower-quality versions [11] - The app prevents duplicate saves of images and videos already stored in the gallery, and allows users to preview files before downloading [12][13] - A sorting feature for large files and more refined filtering options have been introduced to facilitate efficient storage cleaning [14][15] Group 5: Continuous Improvements - Adjustments to the storage space alert system have reduced notification frequency by approximately 90%, with clearer cleaning options provided [16][17] - The entry points for storage management have been made more accessible and faster to load [18]
