I don't know how to say it, I'm embarrassed. Anyway, it's just that after a program runs, it can add the first number in the 10th line of the txt files in the directory. For example:
1: Anonymous 48 321 166.84 100.00% 0 0.00 NaN%
Just add 48, and the following numbers don't need to be cared about.
I mean, for different txt files, just add the numbers in the 48 position.
1: Anonymous 148 321 166.84 100.00% 0 0.00 NaN%
1: Anonymous 48 321 166.84 100.00% 0 0.00 NaN%
1: Anonymous 1148 321 166.84 100.00% 0 0.00 NaN%
The above three txt files are extracted, and the positions of 8 are all the same in one column. After the program runs, calculate the sum of 148 + 48 + 1148.
I have low education, so it's possible that my Chinese level is not enough, sorry.

@echo off
setlocal enabledelayedexpansion
for %%i in (*.txt) do (
    set file=%%i
    set count=0
    for /f "skip=9 tokens=3" %%j in (!file!) do (
       set /a count+=1
       if !count! equ 1 set /a sum+=%%j
    )
)
echo   相加后的结果是 %sum%
pause

By comparing the file you uploaded, I found that there is a space after ":", so ":" should be in the first column of the text, and numbers like 148 are in the third column. To solve your problem, you can try the following code:

@echo off
setlocal enabledelayedexpansion
for %%i in (*.txt) do (
    set file=%%i
    set count=0
    for /f "skip=9 tokens=3" %%j in (!file!) do (
       set /a count+=1
       if !count! equ 1 set /a sum+=%%j
    )
)
echo   The sum result is %sum%
pause

Thank you, it's already solved. I really didn't know what the concept of a column is. Can you help explain it? Thanks

               第    第    第
               一    二    三
               列    列    列

第一行：        1     2     3
第二行：        4     5     6
第三行：        7     8     9
……

As the saying goes, horizontally and vertically. In a text file, the text in the horizontal direction is called a line, and lines are separated by carriage return symbols; the text in the vertical direction separated by spaces or tabs is called a column, as shown below (assuming that Arabic numerals are the content of the text), 1 is in the first row and first column, and 6 is in the second row and third column:

               第    第    第
               一    二    三
               列    列    列

First line:        1     2     3
Second line:       4     5     6
Third line:        7     8     9
……

Hehe, thank you. This forum is really good

There is another question. If these txt files are in a certain directory on another machine in the local area network, can I run a program on my own machine to calculate the sum of the numbers in the txt files under the certain directory on that machine? That machine has the default permissions of opening admin$ and ipc$.
