之前也遇到一样问题 先把icloud的备份删除然后关掉备份 之后把files删除 手机重开 重新从app store把files载回来再把icloud备份开起来p.s. 确定iCloud Drive有开起来 files里面的东西会在云端有备份(Delete your icloud backup and turn it off, then delete the files app, restart your iphone, install the files app again from app store and turn icloud backup on again, should fix the issue. Make sure you have iCloud Drive on before doing this so you won't lose the data in the Files app.)中文不好抱歉
