How can I use a batch file to directly call the system's WinRAR program, no matter which drive the compression program is installed on?!!!

Many thanks to balinger, but I tried running it, and why does it exit after pressing any key to continue? It didn't run the WinRAR program!

@echo off if exist "C:\Program Files\WinRAR\WinRAR.exe" ( set WinRAR_Path=C:\Program Files\WinRAR\WinRAR.exe ) else ( reg export "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\WinRAR.exe" tmp.reg >nul for /f "skip=3 delims== tokens=2" %%a in ('type tmp.reg') do ( set WinRAR_Path=%%~a call set WinRAR_Path=%%WinRAR_Path:\\=\%% del tmp.reg goto next ) ) :next start "" "%WinRAR_Path%" d "archive filename" "filename to delete"
That damn BUG in reg.exe... if I use reg query directly it drops characters, so there's no choice but to export first.

What I want is to write a batch file to traverse the system's rar archives and call the WinRAR command line to delete a certain file inside the rar archives. How should this batch file be written? Thanks!!! winrar d deletes files inside an archive.

The code in post #4 has been updated.

I tried running it and got an error. :（

What is the error message?

Let me explain it more clearly. I want to write a batch file to traverse the system's rar archives, and if an archive contains 1.exe, call the WinRAR command line to delete the program 1.exe from that rar archive. How should this batch file be written? Thanks!!! winrar d deletes files inside an archive.

Windows cannot find the file 'C:\Program'. Please make sure the filename is correct, and then try again. To search for a file, click the "Start" button, and then click "Search".

OK

for /d %%i in (C,D,E,F,G,H,I,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z\*.rar) do (
IF exist %%i: (
winrar.exe d %%c\*.rar 1.exe
)
)
This is what I wrote, definitely not correct. This only traverses archive files under the root directories of the drives.

Sorry, I got one part wrong. Try the code in post #4 again.

Many thanks to tireless, the program can run now, but it doesn't seem to have achieved the effect I expected.

This only searches for .rar files under the root directories of the drives:
@echo off if exist "C:\Program Files\WinRAR\WinRAR.exe" ( set WinRAR_Path=C:\Program Files\WinRAR\WinRAR.exe ) else ( reg export "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\WinRAR.exe" tmp.reg >nul for /f "skip=3 delims== tokens=2" %%a in ('type tmp.reg') do ( set WinRAR_Path=%%~a call set WinRAR_Path=%%WinRAR_Path:\\=\%% del tmp.reg goto next ) ) :next for %%A in (c d e f g h i j k l m n o p q r s t u v w x y z) do ( if exist %%A: ( for %%a in (%%A:\*.rar) do ( start "" "%WinRAR_Path%" d -INUL "%%a" "1.exe" ) ) )

If you want to search for .rar files including subdirectories, change:

for %%a in (%%A:\*.rar)

to:

for /r %%A: %%a in (*.rar)
