index-https.html ~~It requires a folder with the same name

Hello. Now the cache of WP super cache plug-in is in the cache folder. The cache file of the home page of the website is not in the folder. Because my website has too many subfolders, I seriously doubt that it affects the efficiency. Excuse me, how can I change the cache file of the home page to appear in its named subfolder.

你好。现在wp super cache插件的缓存都在cache文件夹中。网站首页的缓存文件并不在文件夹中。因为我的网站有超多子文件夹，严重怀疑这样它影响了效率。请问，如何更改才能让 首页的缓存文件 也出现在它命名的子文件夹中。
