当事人的 PR 提供的代码已经几乎被全部移除。介于当事人的努力依然值得尊重，我并没有完全在 Git 层面移除他的提交。因此，当本 PR 合并后，当事人依然会有 Co-Author 信息

EDIT: 换而言之，这不是修改，而是重写

I tested the refactored code and it looks good.

Thanks to the fact that the log files are stored in UTF-8 encoding, CJK characters can also be displayed normally. For disabled mods, mods replaced during updates, and mods with different suffixes (tested with .zip and .litemod), they can also be displayed normally.

Thanks for your testing.

Using Files.walkFileTree, which is an API from standard java library could prevent potential bugs or risks from using Files.listFiles. And, with this structure, it's easies to list files from .zip files with less edit.
