基于Python怎么編寫微信清理工具

這篇“基于Python怎么編寫微信清理工具”文章的知識點大部分人都不太理解，所以小編給大家總結了以下內容，內容詳細，步驟清晰，具有一定的借鑒價值，希望大家閱讀完這篇文章能有所收獲，下面我們一起來看看這篇“基于Python怎么編寫微信清理工具”文章吧。

主要功能

它可以自動刪除 PC 端微信自動下載的大量文件、視頻、圖片等數據內容，釋放幾十 G 的空間占用，而且不會刪除文字的聊天記錄，可以放心使用。

工作以后，微信的群聊實在太多了，動不動就被拉入一個群中，然后群聊里大部分都是與自己無關的各大群聊中的文件、視頻、圖片等內容，會非常占用存儲空間。

• 自動識別微信賬號，支持用戶選擇自定義路徑；

• 同時管理多個賬號，保留配置參數，打開即用；

• 自由設置想要刪除的文件類型，包括圖片類緩存、文件、圖片、視頻；

• 自由設置需要刪除的文件的距離時間，默認 365 天；

• 刪除后的文件放置在回收站中，檢查后自行清空，防止刪錯文件；

• 支持刪除進度的顯示；

工具的主界面如下

運行環境

Windows，后續可能會支持 Mac。
