所需工具：微信APP。
具体步骤如下：
1、首先，进入微信的设置界面，找到通用。

2、然后，在通用界面中，打开照片、视频和文件。

https://iknow-pic.cdn.bcebos.com/962bd40735fae6cdbf478f1a01b30f2443a70fdd"/>
3、将照片、视频和文件中的三个选项全部关掉。

https://iknow-pic.cdn.bcebos.com/8b82b9014a90f6039571b83c3712b31bb151ed8c"/>
4、返回通用界面，找到最下方的微信存储空间。

https://iknow-pic.cdn.bcebos.com/d4628535e5dde711f9e5648da9efce1b9d166191"/>
5、在微信存储空间中，点击管理微信存储空间。

https://iknow-pic.cdn.bcebos.com/e824b899a9014c08905e0fde047b02087bf4f460"/>
6、对聊天数据进行分类清理，就可以释放几个G的空间了。
