andineck, Thank you very much.

The sort directory entries is better to character languages, like english; but is not to the grapheme languages, like Chinese or Japanese. So, I give an option for users by adding "num-" prefix. Do you have a better idea?

[andineck]

@imfly Thank you for merging the PR. Sorry for my late answer. I think in general it is good to have the directories listed before the files. Is there already an option to switch off the "num-" prefix auto removing from the Links? I have several files that have "-" in the name and the first part get's removed automatically, even though it's not a number. If it is possible to switch off this behaviour, that would also be helpful. What do you think?

@andineck Yes，if the prefix is "num-" or "azAZ-", the prefix will be uesed to order defaultly, #6

I'm going to switch off this behaviour defaultly for character languages, like english. And users can add the "num-" prefix for the grapheme languages, like Chinese or Japanese.
