基于Python怎么编写微信清理工具

这篇“基于Python怎么编写微信清理工具”文章的知识点大部分人都不太理解，所以小编给大家总结了以下内容，内容详细，步骤清晰，具有一定的借鉴价值，希望大家阅读完这篇文章能有所收获，下面我们一起来看看这篇“基于Python怎么编写微信清理工具”文章吧。

主要功能

它可以自动删除 PC 端微信自动下载的大量文件、视频、图片等数据内容，释放几十 G 的空间占用，而且不会删除文字的聊天记录，可以放心使用。

工作以后，微信的群聊实在太多了，动不动就被拉入一个群中，然后群聊里大部分都是与自己无关的各大群聊中的文件、视频、图片等内容，会非常占用存储空间。

• 自动识别微信账号，支持用户选择自定义路径；

• 同时管理多个账号，保留配置参数，打开即用；

• 自由设置想要删除的文件类型，包括图片类缓存、文件、图片、视频；

• 自由设置需要删除的文件的距离时间，默认 365 天；

• 删除后的文件放置在回收站中，检查后自行清空，防止删错文件；

• 支持删除进度的显示；

工具的主界面如下

运行环境

Windows，后续可能会支持 Mac。
