使用批处理文件在目录中递归地删除所有特定类型(扩展名)的文件

小开

最佳答案

You can use wildcards with the del command, and /S to do it recursively.

del /S *.jpg

Addendum

@BmyGuest asked why a downvoted answer (del /s c:\*.blaawbg) was any different than my answer.

There's a huge difference between running del /S *.jpg and del /S C:\*.jpg. The first command is executed from the current location, whereas the second is executed on the whole drive.

In the scenario where you delete jpg files using the second command, some applications might stop working, and you'll end up losing all your family pictures. This is utterly annoying, but your computer will still be able to run.

However, if you are working on some project, and want to delete all your dll files in myProject\dll, and run the following batch file:

@echo off


REM This short script will only remove dlls from my project... or will it?


cd \myProject\dll
del /S /Q C:\*.dll

Then you end up removing all dll files form your C:\ drive. All of your applications stop working, your computer becomes useless, and at the next reboot you are teleported in the fourth dimension where you will be stuck for eternity.

The lesson here is not to run such command directly at the root of a drive (or in any other location that might be dangerous, such as %windir%) if you can avoid it. Always run them as locally as possible.

Addendum 2

The wildcard method will try to match all file names, in their 8.3 format, and their "long name" format. For example, *.dll will match project.dll and project.dllold, which can be surprising. See this answer on SU for more detailed information.

If you are trying to delete certain .extensions in the C: drive use this cmd:

del /s c:\*.blaawbg

I had a customer that got a encryption virus and i needed to find all junk files and delete them.

I wrote a batch script a while ago that allows you to pick a file extension to delete. The script will look in the folder it is in and all subfolders for any file with that extension and delete it.

@ECHO OFF
CLS


SET found=0
ECHO Enter the file extension you want to delete...
SET /p ext="> "


IF EXIST *.%ext% (           rem Check if there are any in the current folder :)
DEL *.%ext%
SET found=1
)
FOR /D /R %%G IN ("*") DO (  rem Iterate through all subfolders
IF EXIST %%G CD %%G
IF EXIST *.%ext% (
DEL *.%ext%
SET found=1
)
)


IF %found%==1 (
ECHO.
ECHO Deleted all .%ext% files.
ECHO.
) ELSE (
ECHO.
ECHO There were no .%ext% files.
ECHO Nothing has been deleted.
ECHO.
)


PAUSE
EXIT

Hope this comes in useful to anyone who wants it :)

You can use this to delete ALL Files Inside a Folder and Subfolders:

DEL "C:\Folder\*.*" /S /Q

Or use this to Delete Certain File Types Only:

DEL "C:\Folder\*.mp4" /S /Q
DEL "C:\Folder\*.dat" /S /Q

I don't have enough reputation to add comment, so I posted this as an answer. But for original issue with this command:

@echo off
FOR %%p IN (C:\Users\vexe\Pictures\sample) DO FOR %%t IN (*.jpg) DO del /s %%p\%%t

The first For is lacking recursive syntax, it should be:

@echo off
FOR /R %%p IN (C:\Users\vexe\Pictures\sample) DO FOR %%t IN (*.jpg) DO del /s %%p\%%t

You can just do:

FOR %%p IN (C:\Users\0300092544\Downloads\Ces_Sce_600) DO @ECHO %%p

to show the actual output.

this is it:

@echo off


:: del_ext
call :del_ext "*.txt"
call :del_ext "*.png"
call :del_ext "*.jpg"


:: funcion del_ext
@echo off
pause
goto:eof
:del_ext
set del_ext=%1
del /f /q "folder_path\%del_ext%"
goto:eof

pd: replace folder_path with your folder

Step 1: Navigate to the folder in question using the cd command

For example: cd C:\Users\tremanleo\Desktop\HoldLEOCMS

Step 2 Delete the the file type.

For Example: DEL *.bak
