It seems not. Just change "第1章.txt" to "第01章.txt" and it will be okay.

You need to replace the "×" in Chapter × with a two-digit number, padding with 0 in front if it's less than two digits, and then sort them in ascending order? After looking at the descriptions of your two floors, I'm still not very sure about exactly what purpose you want to achieve. Please make your meaning clear.

Also, is this "×" only in Arabic numeral format? Please state the complete requirement so that it's easier to write code.

The requirements of the thread starter itself have no pattern

Is my language really bad? The second time someone couldn't understand what I meant!!!!!!! Sweat!!!!!!!
I mean the original file names are from Chapter 1 to Chapter 29, and I don't change the original file names. DIR a folder > 1.txt, and the TXT text should be arranged from small to large. Don't arrange like the first one above where 10-19 are arranged first, then 1, then 20-29, then 2, then 3-9!!My purpose is to get the arrangement from 1-9, then 10-19, then 20-29 like this!!! Because it's difficult to generate other files that can be sorted in ascending order with batch (or I'm not capable enough?), so only the Arabic numeral format is considered!! Also, if I use batch to generate files named 01-20 like this, how should the FOR statement be written? The method of reading variables from the text is not considered.

sort 不知道可以吧？

```
dir /b 第?章.txt > List.txt && dir /b 第??章.txt >> List.txt


The obtained file list is stored in the List.txt file:
Chapter 1.txt Chapter 2.txt Chapter 3.txt Chapter 4.txt Chapter 5.txt Chapter 6.txt Chapter 7.txt Chapter 8.txt Chapter 9.txt Chapter 10.txt Chapter 11.txt Chapter 12.txt Chapter 13.txt Chapter 14.txt Chapter 15.txt Chapter 16.txt Chapter 17.txt Chapter 18.txt Chapter 19.txt Chapter 20.txt Chapter 21.txt Chapter 22.txt Chapter 23.txt Chapter 24.txt Chapter 25.txt Chapter 26.txt Chapter 27.txt Chapter 28.txt Chapter 29.txt
