Core Viewpoint - The article addresses common concerns regarding WeChat's storage space usage, providing clarifications on various aspects of data storage and management within the app. Group 1: File Storage and Deletion - WeChat does not duplicate storage when forwarding the same file to multiple friends, utilizing a "hard link" technology to maintain a single copy of the file [2] - Deleted chat records do not occupy space as WeChat employs an "asynchronous deletion" mechanism to ensure user experience is not interrupted [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: Storage Management and Notifications - WeChat prompts users about insufficient storage to protect chat records from potential loss, with notification thresholds set at 700MB for iOS and up to 1GB for Android [7] - Disabling "auto-download" may alleviate storage issues for users logged into multiple devices, but it may compromise the completeness of chat records on the primary device [8] Group 3: Application Size and Necessary Files - The increase in WeChat's installation package size over the years is attributed to the addition of features and resources, although recent optimizations have led to a decrease in the package size for the latest Android version [9] - "Necessary files" are defined as those essential for the app's operation, including code files and user configuration data, and WeChat is working to optimize the storage of these files [10] Group 4: User Data and Cache Management - New features developed based on user demand do not necessarily lead to increased storage usage, as many generate cache data that can be cleared without affecting functionality [11] - For users experiencing significant storage usage (over 40GB), chat records account for an average of 70% of the total space occupied [11]
