前几天网上找了一款 PC 端微信自动清理工具，用了一下，电脑释放了 30GB 的存储空间，而且不会删除文字的聊天记录，很好用，感觉很多人都用得到，就在此分享一下，而且是用 Python 写的，喜欢 Python 的小伙伴可以探究一下。
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。
