**Purpose**: Automatically delete 1.exe after self-extraction

**Process**: I created a self-extracting file (such as 1.exe), which only contains a 1.bat. The self-extraction directory is in %systemroot%. I wanted to automatically delete 1.exe after extraction, so I added del /q/f 1.exe. As a result, I couldn't find the path of 1.exe.

Attempt 1: Set the self-extraction directory to. \, which is the current directory. In this way, 1.exe can be automatically deleted, but there will be a certain display delay. This situation is not discussed for the time being;

Attempt 2: Create a 1.bat (content: @echo %cd% > c:\cpath.txt), set it as "Run before extraction", then create a 2.bat
@for /f "tokens=*" %%i in (c:\cpath.txt) do set cpath=%%i
@del /q /f "%cpath%\1.exe"
As a result, the read "%cpath%" is the path where %systemroot% is located, and it failed, heh heh

Attempt 3: Create a 1.bat and 2.bat. Create a self-extracting file 2.exe for 2.bat, and set the extraction directory to %systemroot%; create a self-extracting file 1.exe together with 1.bat and 2.exe, and set the extraction directory to the current directory. The original idea was: use 1.bat to extract the current path and copy 2.exe to the %systemroot% directory, then run 2.exe to delete the generated files. Just when deleting 1.exe, the "Access denied." always appears, and I can't get over this hurdle. I still want everyone to help give some advice, thank you.

**Solution**: The method is like "Attempt 3". The contents of the two files are as follows:
1.bat

@echo off

echo %cd% > c:\windows\cpath.txt

start "hehe" "%cd%\2.exe"  >nul

del /q /f %0 >nul

2.bat

@echo off

@for /f "tokens=*" %%i in (c:\windows\cpath.txt) do set cpath=%%i

set "cpath=%cpath:~0,-1%"

taskkill /f /im 1.exe >nul

taskkill /f /im 2.exe >nul

del /f /q c:\windows\cpath.txt >nul

del /f /q "%cpath%"\1.exe  >nul

del /f /q "%cpath%"\2.exe  >nul

del /f /q %0 >nul

:)

The code is still a bit messy. I hope everyone doesn't mind. Also, thank you to the brother on floor 9 for the advice.
This code was tested and passed under xp+sp2.

It seems that there is an option in WinRAR to delete the self - contained compressed file.

Thank you lianjiang2004, can you be more specific?

Is to delete its own file

Add DEL 1.EXE after BAT, and also add DEL %0,
Use the Phantom mode of QBFC.

Adding DEL %0 is to delete the bat itself, or can't delete the self-extracting file, heh heh

Thanks

Still hope brothers can give some suggestions, thank you thank you thank you

Add DEL/q [self-extracting file path and file name] at the end of the batch processing.

Tips:
To delete an executable file,
this file must not be running in the Windows system (the one that is executing cannot be deleted)

This problem can be solved by using delay instructions + writing code.

After testing, the delay does not have the expected effect. I don't know if it's due to the local machine. I have to use taskkill.

A friend named 10 had a fresh idea. He used taskkill to end the WinRAR process and reversed to solve this problem. Nice! Add points.
