七八年前用的百度云同步云相册，照片都同步上去了，现在改用nas，照片下载下来后发现照片的拍摄时间等等都没有了， 另外百度是按照上传时间命名，这跟拍摄时间怎么对起来？？？

照片上传到nas后，按照时间线排序上千张照片都在一天内，怎么看？？？

网上找到了，批量修改照片日期的方法，记录一下。

首先按照vs code，官网地址https://code.visualstudio.com/，下载很慢可以修改一下下载链接

# Change photo name by photo date/time and vice versa.
# 功能：
# 1. 根据照片名称修改照片日期：根据照片名中包含的日期信息，修改照片Exif中的日期信息
# 2. 根据照片日期修改照片名称：根据照片Exif中的日期信息，按照统一格式重命名照片

安装完成后按我的操作进行插件下载

然后使用cmd安装

pip install Pillow

pip3 install datetime
