It's correct. However, I've just tested that and it looks like it doesn't only rely on the date info, but also on the hours and minutes. +7will then remove the files older than 168hours. I have some similar set up, please have a look on that:
这是正确的。但是，我刚刚对其进行了测试，看起来它不仅依赖于日期信息，还依赖于小时和分钟。+7然后将删除早于168小时的文件。我有一些类似的设置，请看一下：
