Solved, see http://www.cn-dos.net/forum/viewthread.php?tid=27658&page=1&sid=FB2nu4#pid174202 Post 2 building ZH159 brother's answer.

Below is my code, please modify

@ECHO OFF

SET PATH=%CD%;%CD%\TOOLS\;%PATH%



FOR /F "EOL=;DELIMS=" %%I in (.\Purge\PurgeS.SVE) DO (

    ECHO Compressing and backing up files under %windir%\%%I\, please wait... 

    PING 127.0.0.1 -n %TIMEOUT% >NUL

    RAR.EXE A -EP3 -IDQ ".\BACKUP\%%~nI" "%windir%\%%I"

)

PAUSE

The content in PurgeS.SVE is as follows:

; Here you can set the system-level garbage files to be backed up and cleaned. They must be represented by folders and must be represented with %windir% as the root.

; If font cleaning is set, you need to set the font files to be retained in FONTS.SVE.

; Input method cleaning should be carried out separately in IME.SVE.

;

;

; Folders that can be backed up and cleaned. If you want to retain them, use ; to comment out the items to be cleaned; you can also add the contents of other folders that need to be backed up and cleaned, such as the wallpapers under Web\Wallpaper

; Fonts

FONTS

; Help

HELP

; Help support center

PCHealth

; Driver cache

Driver Cache

; DLL cache

SYSTEM32\dllcache

; System repair backup

REPAIR

; Prefetch

prefetch

; Search assistant

srchasst

; Microsoft Agent

msagent

; System activation (only for VOL version)

; system32\oobe

Everyone should have understood the meaning of my code. I am using the RAR program to compress and back up all the files in the folder specified in PurgeS.SVE to the current BACKUP directory. But when running to SYSTEM32\dllcache with subdirectories, an error occurs, prompting that the path of the compressed file to be backed up is not found. Because I want to back up directly to the BACKUP directory regardless of whether there are subdirectories, and determine the name of the compressed file with the name of the last subdirectory of the directory. For example, the backup of SYSTEM32\dllcache should be dllcache.rar and must be in the BACKUP directory.

I hope everyone can give me a solution idea or code. It is required to use batch processing, not use VBS, and the running environment is WINXP. Thank you.

Regarding the RAR command, I just sent my study notes to http://www.cn-dos.net/forum/viewthread.php?tid=27657&sid=FB2nu4, which can be referred to.


There is a new problem in building 17, waiting online for the masters' answer again

### Step 1: Analyze the code
- `Str1 = "C:\WINDOWS\IME\CINTLGNT"`: This is a string variable assigned a path.
- `Pos = InstrRev(Str1, "\")`: `InstrRev` is a function to find the last occurrence of a character in a string. Here, it finds the last backslash in `Str1`.
- `mid(Str1, Pos + 1, len(Str1) - Pos)`: `Mid` function is used to extract a substring. It starts from the position after the last backslash and takes the remaining characters.

### Step 2: Translate the code's functionality description (since the code itself is in English-like structure but we need to ensure correct translation of the logic description)
The code first defines a string `Str1` with a path, then finds the position of the last backslash in `Str1`, and then extracts the substring starting from the character after the last backslash.

In terms of the final result, the code will extract the last part of the path after the last backslash. The translated code execution result is that the message box will display "CINTLGNT".

But according to the requirements, we just translate the original text as per the rules. The original code is in a programming language (VBScript like), and when translating the content:

The code lines are:
```vb
dim Str1,Pos
Str1="C:\WINDOWS\IME\CINTLGNT"
Pos=InstrRev(Str1,"\")
msgbox mid(Str1,Pos+1,len(Str1)-Pos)
```

Translated:
```vb
dim Str1, Pos
Str1 = "C:\WINDOWS\IME\CINTLGNT"
Pos = InstrRev(Str1, "\")
msgbox Mid(Str1, Pos + 1, Len(Str1) - Pos)
```

The result of running this code is to display "CINTLGNT" in the message box. But following the instruction to just provide the translated text as per the input, the translated code is as above, and the result of the code is "CINTLGNT". So the final output related to the translation of the code content is:

```vb
dim Str1, Pos
Str1 = "C:\WINDOWS\IME\CINTLGNT"
Pos = InstrRev(Str1, "\")
msgbox Mid(Str1, Pos + 1, Len(Str1) - Pos)
```

And the actual value shown in the message box is "CINTLGNT"

Thanks for the answer, I want to use batch processing, not VBS

for /f "tokens=*" %? in ('dir /ad/b c:\') do (echo %?|sed -r "s/.*\\([^\]*)$/\1/")

### Principle of getting the substring after the last "\" in the path :)

FOR /?

%~nI - Expand %I to a file name only

I don't want to use SED, thank you Brother VKILL for your answer. Is there any other way?

### Re: 获取路径最后一个"\"后的字串原理：）

Thanks for REDTEK brother's answer, but I use it as follows, it seems wrong, can you modify it.

@ECHO OFF

SET PATH=%CD%;%CD%\TOOLS\;%PATH%



FOR /F "EOL=;DELIMS=" %%I in (.\Purge\PurgeS.SVE) DO (

    ECHO Compressing and backing up files under %windir%\%%I\, please wait a moment...... 

    PING 127.0.0.1 -n %TIMEOUT% >NUL

    RAR.EXE A -EP3 -IDQ ".\BACKUP\%%I:%~nI" "%windir%\%%I"

)

PAUSE

@echo off
FOR /F "EOL=;DELIMS=" %%I in (PurgeS.SVE) DO (
ECHO Compressing and backing up files under %windir%\%%I\, please wait...
PING 127.0.0.1 -n %TIMEOUT% >NUL
for /F "tokens=2 DELIMS=\" %%J IN ("%%I") do echo ".\BACKUP\%%J" "%windir%\%%I"
echo ".\BACKUP\%%I" "%windir%\%%I"
)
PAUSE

Thanks brother again for the answer, but because the number of path levels is not fixed, so using your this method still doesn't work. Your this DELIMES=2 only has 2 levels. What if there are 3 levels, 4 levels?

Let me explain again the reason why I get the last name of the directory with \ is that it is convenient for me to use the RAR command to restore again. For example, if I have backed up all items, then I can let the user choose the content to restore, such as Japanese input method, Korean input method, MS Pinyin input method, etc. If it is directly compressed into one or a certain package as a whole, it is very inconvenient to use the RAR command for restoration

I'm very grateful to Brother zh159 for answering my question many times. I should learn from you a lot.

Just now, Brother redtek also answered my question. Because I'm not familiar with the FOR statement at all, I still didn't understand Brother redtek's meaning. I actually treated it as a SET variable and made it %%I:%~nI, so no matter how I did it, it didn't come out.

Thank you again for your answer.

Also thank you~
Still a lot to go with the for in bat..

Hey, I actually forgot to use %~ni
