    Windows不允许在同一个目录下创建文件夹a，文件夹A，系统会认为它们是重名的。

请参考Q-04和Q-05把bat文件和txt文件都保存为ANSI编码：

@echo off
setlocal enabledelayedexpansion
set "MergeFile=All.txt"
>"%MergeFile%" type nul
for %%a in ("a" "b" "c") do (
    pushd %%a
    for /f "delims=" %%i in ('dir /b /a-d') do (
        set "_%%~nxa_!random!=%%~nxa\%%i"
    )
    for /f "tokens=2 delims==" %%i in ('set _%%~nxa') do (
        set "RandFile=%%i"
    )
    popd
    >>"%MergeFile%" type "!RandFile!"
    >>"%MergeFile%" echo,
)

第二种思路

@echo off
setlocal enabledelayedexpansion
set "MergeFile=All.txt"
>"%MergeFile%" type nul
for %%a in ("a" "b" "c") do (
    pushd %%a
    set n=0
    for /f "delims=" %%i in ('dir /b /a-d') do (
        set /a n+=1
        set "_!n!=%%~nxa\%%i"
    )
    set /a RandNum=!random!%%^(3-1+1^)+1
    call set "RandFile=%%_!RandNum!%%"
    popd
    >>"%MergeFile%" type "!RandFile!"
    >>"%MergeFile%" echo,
)

20200812为文件夹 *.txt的为文件。需要把从20200812文件夹名称开始到20200915结束文件夹下所有的table.txt结尾的文件 输出到onlinetale.txt文件中，data.txt结尾的文件输出到onlinedata.txt

test1.bat

@echo off
type nul >"onlinetale.txt"
type nul >"onlinedata.txt"
for /f "delims=" %%i in ('dir /b /ad') do (
    dir /b /a-d "%%i\*table.txt" >>"onlinetale.txt"
    dir /b /a-d "%%i\*data.txt" >>"onlinedata.txt"
)
复制代码

test2.bat

@echo off
type nul >"onlinetale.txt"
type nul >"onlinedata.txt"
for /f "delims=" %%i in ('dir /b /ad') do (
    (for /f "delims=" %%j in ('dir /b /a-d "%%i\*table.txt"') do (
        type "%%j"
    ))>>"onlinetale.txt"
    (for /f "delims=" %%j in ('dir /b /a-d "%%i\*data.txt"') do (

    有一小部分不太准确，"_!n!=%%~nxa\%%i"蓝色是文件名及扩展名，红色是文件夹名
