自动判断文件夹是否为空。是空文件夹则删除！
使用 LLM 解释/回答一下
自动判断文件夹是否为空。是空文件夹则删除！
for /l %%a in (1,1,3) do for/r %%i in (.) do rd %%~si
帮我看看这个有没有什么错误。。
可以用在LJ 文件清理里面么？
Automatically determine whether a folder is empty. If it is an empty folder, delete it!
for /l %%a in (1,1,3) do for/r %%i in (.) do rd %%~si
Let me see if there are any errors.
Can it be used in LJ file cleaning?

的确厉害
学习了
致敬
0字节的所有类型的文件
用FOR中的%%~z扩展文件大小
%%~zi=0就是0字节i
Indeed powerful
Learned
Salute
All types of files with 0 bytes
Use %%~z in FOR to expand the file size
%%~zi=0 means 0 bytes i

就是利用rd命令的特性，在删除0字节文件夹时不会提示出错
It is to use the characteristics of the rd command. When deleting a 0-byte folder, it will not prompt an error.

把"|:\"
去掉就表示当前盘符
把"|:\"替换为自己的路径即可

Removing "|:\" means the current drive letter.
Replace "|:\" with your own path.

比如:你要删C盘下.空文件夹:
for /f "tokens=*" %%a in ('dir /b /ad /s "c:\"^|sort /r') do rd "%%a" 2>nul
你要删d盘下.空文件夹:
for /f "tokens=*" %%a in ('dir /b /ad /s "d:\"^|sort /r') do rd "%%a" 2>nul

Thanks!
For example: You want to delete empty folders under the C drive:
for /f "tokens=*" %%a in ('dir /b /ad /s "c:\"^|sort /r') do rd "%%a" 2>nul
You want to delete empty folders under the D drive:
for /f "tokens=*" %%a in ('dir /b /ad /s "d:\"^|sort /r') do rd "%%a" 2>nul

为什么将2＃的
for /f "tokens=*" %%a in ('dir /b /ad /s "E:\"^|sort /r') do rd "%%a" 2>nul
改为：
for /f "tokens=*" %%a in ('dir /b /ad /s "E:\"^|sort /r') do echo "%%a">>空文件夹菜单.txt
写入记事本的却是所有文件夹呢？
Why does changing the
for /f "tokens=*" %%a in ('dir /b /ad /s "E:\"^|sort /r') do rd "%%a" 2>nul
to:
for /f "tokens=*" %%a in ('dir /b /ad /s "E:\"^|sort /r') do echo "%%a">>空文件夹菜单.txt
result in all folders being written to the notepad?

是会列出所有文件夹的，至于为什么只删除空的文件夹而不删除非空文件夹
就是利用rd命令的特性，在删除空文件夹时不提示
在未加/Q参数时，rd命令在删除非空文件夹时，会提示出错信息的。

will list all folders. As for why it only deletes empty folders and not non-empty ones
it is because of the characteristic of the rd command. When deleting an empty folder, it does not prompt
When the /Q parameter is not added, the rd command will prompt an error message when deleting a non-empty folder.

for /f "tokens=*" %%a in ( ...
'dir /b /ad /s "E:\"^|sort /r'
此命令用于列出所有E盘下及其子目录（/s）的文件夹名（/ad）
/ad指定了打印文件夹名
然后把文件夹名赋值给%%a
2>nul
的意思是把rd "%%a"命令执行时出现的错误命令写入空设备（就是不需要反馈了）
改成 echo "%%a" >>aaa.txt
当然就是把删除空文件时的系统反馈写入aaa.txt
因为%%a就是文件夹名

to:
for /f "tokens=*" %%a in ( ...
'dir /b /ad /s "E:\"^|sort /r'
This command is used to list all folder names (with /ad) under and in subdirectories (/s) of drive E:
/ad specifies to print folder names
Then assign the folder name to %%a
2>nul
means to write the error commands when executing the rd "%%a" command to the null device (that is, no feedback is needed)
Changing it to echo "%%a" >>aaa.txt
Of course, it is to write the system feedback when deleting empty files to aaa.txt
Because %%a is the folder name
