To intercept the character "KB832353" in the following paths:

First path: "Microsoft\Updates\Windows Media Player\KB832353"
The part after the last backslash "\" is "KB832353", so you can use string manipulation methods to get the substring starting from the last backslash.

Second path: "Microsoft\Updates\Windows Media Services\KB832359"
Here the relevant part is not "KB832353".

The specific way to intercept depends on the programming language you are using. For example, in Python:

For the first path string, you can do:

path = r"Microsoft\Updates\Windows Media Player\KB832353"
start_index = path.rfind("\\") + 1
kb_number = path
print(kb_number)

This will extract "KB832353" from the first path.

In Java:

String path = "Microsoft\\Updates\\Windows Media Player\\KB832353";
int lastBackslashIndex = path.lastIndexOf("\\");
String kbNumber = path.substring(lastBackslashIndex + 1);
System.out.println(kbNumber);

So the intercepted character "KB832353" can be obtained through such string operation methods.

@echo off

for /f "tokens=4 delims=\" %%i in ('sort/r 1.txt') do set a=%%i

echo %a%

pause>nul

```@echo off
for /f "tokens=4 delims=\" %%i in ('sort/r 1.txt') do set a=%%i
echo %a%
pause>nul
```

@echo off

for /f "delims=" %%a in (1.txt) do (

	Setlocal EnableDelayedExpansion

	set a=%%a

	set a=!a: =!

	echo !a:~-8!

	Endlocal

)

pause

@echo off

for /f "delims=" %%a in (1.txt) do (

	Setlocal EnableDelayedExpansion

	set a=%%a

	set a=!a: =!

	echo !a:~-8!

	Endlocal

)

pause

@echo off

for /f "delims=" %%i in (1.txt) do echo "%%~nxi"

pause

Using for extension, make a more concise code:

@echo off

for /f "delims=" %%i in (1.txt) do echo "%%~nxi"

pause

The idea of the moderator is very good. If you want to only display KB832353, you need to make some changes.

%%~nxi This is very good

　　namejm used this cleverly~

The method of the 4th floor is good. But if I want to extract the middle part, how about "Windows Media Player" in "Microsoft\Updates\Windows Media Player\KB832353"?

This question has been discussed before. Extracting strings at any level is not a difficult problem. Please see post 14 of this thread: How to get the last part of the filename in the absolute path? .

Hehe, thanks. Still digesting.

I want to make a small suggestion. I wonder if a bookmarking function can be added? After all, many newbies can't fully grasp everything at once, and it's difficult to find the specified post when they want to check it. With the bookmarking function, everything will be more convenient.

There are collections. It's at the bottom of the web page.

I've learned about the usage of tokens again

Solving one question in multiple ways, learning something!
