}重要 目前只支持删除一年内的截图文件。

截图文件时间戳可通过查询截图文件获取。详情可参见查看截图文件。

对于覆盖截图的截图文件，目前只能在OSS中进行删除，具体操作可参见OSS删除文件。

更多删除直播截图文件接口说明，请参见DeleteSnapshotFiles。

以上示例实现了对截图文件的删除（同时删除了储存在OSS中的文件）。

您可以为截图功能设置回调事件，获取回调参数将截图信息保存至您自己的业务系统（同时储存时间戳），在需要删除文件时，您就可以根据您系统的策略（如通过定时任务每天定时删除N个月以前的截图文件）查询出截图文件时间戳对截图文件进行删除。若想了解截图回调，可参见直播截图回调开发指南。
