You can just directly change the file name.
It's wrong if it's wrong after being corrected
Can I change the file extension? I've never heard of the CHM format.
Who cares, as long as it can be changed.
It seems that Baiyue can be opened directly; you can download it from BaoRuan website. Java files, CHM format ones I haven't seen yet. Baiyue can open TXT, UMD, CHM. This format probably cannot be converted.
