今天雨松MOMO无意间发现了一个更好的方法来监听Project视图中资源的 创建 删除 移动 保存。把如下脚本放在unity工程中即可，推荐放在Editor目录下。

另外注意一下， 此方法是监听将要进行 创建 删除 移动 保存 的操作， 也就是程序到下一帧才会真正执行 创建 删除 移动 保存。

捐 赠写博客不易，如果您想请我喝一杯星巴克的话？就进来看吧!
OnWillSaveAssets这段代码会导致对文件重命名功能失效，会报错。
而且，对移动和删除的返回值进行修改，也不能阻止这些操作
请问，这些问题，要怎么解决呢？
具体用处是什么呢，比如导入图片自动压缩格式？
这是是一种用法，我想做的是监听删除 更改事件。来同步更新 prefab 里的 prefab 这种情况。
