Batch File to Delete Files in Folders

Question

I have many folders in a directory that contain various files. Each filename begins with XXX_ where XXX could be the name of the folder the file is in. What I am needing to do is to go through all those folders and delete any file where XXX is the name of the folder that file is in.

Answer 1

Please have an eye out this question: Iterating through folders and files in batch file? .

I think this should help you.

Please let me know if you need further assistance.

EDIT #1

The joker character in DOS command line is * . Then, while searching a directory for certain files, you may consider your regular expression, that is, your XXX_ , and complete it with * , this shall return only the files for which you're looking for.

This means that instead of *.zip pattern in one of the FOR loops given the linked question, your first FOR loop should contain your directory name, then take this variable concatenated with the * character to obtain only the files you're looking for.

For example, consider trying the following:

dir /s XXX_*.*

This should return only the files you're interested in, given the right folder name.

EDIT #2

Thanks for having precised your concern.

Here is a code sample that, I do hope so, should help. Now I know you say you have the looping correct, so that perhaps only piece of this code might be needed.

@echo off

setlocal enableextensions enabledelayedexpansion

for /F "delims==" %%d in ('dir /ogne /ad /b /s .') do (
    for /F "delims==" %%f in ('dir /b "%%d\%%~nd_*.*"') do (
        echo %%d\%%f
    )
)

endlocal

This works and lists the files contained in subfolders from the current ( . ) folder.

I have tested it from the following folder:

C:\\Docume~1\\marw1\\MyDocu~1\\MyMusi~1

Where a 'XXX' folder is contained. This 'XXX' folder contains the following files:

1. Copy of XXX_blah.bmp;
2. XXX_blah.bmp;
3. XXX_1234.ppt;
4. XXX_textfile.txt.

From this structure, the output is:

C:\\Docume~1\\marw1\\MyDocu~1\\MyMusi~1\\XXX\\XXX_blah.bmp C:\\Docume~1\\marw1\\MyDocu~1\\MyMusi~1\\XXX\\XXX_1234.ppt C:\\Docume~1\\marw1\\MyDocu~1\\MyMusi~1\\XXX\\XXX_textfile.txt

I then suspect that putting a del instruction instead of an echo command shall do the trick. This means that to isolate the foldername itself from its path, you need to use the ~n instruction with your folder variable name like %%~nd , where your iterating folder variable name is %%d .

Furthermore, you could even use a parameterized batch file in the process, instead of hardcoding it, that is, if your 'set YourFolder =...' is part of your production code. This could look like:

@echo off

setlocal...

set root = %1
set root = %root:~1%
set root = %root:~0,-1%

...

endlocal

Instead of having '.' as pictured in my first FOR loop, your would replace it with "%root%" in order to consider your command line parameter instead of a hardcoded filepath.

I do help this helps, sincerely!

Answer 2

cd C:\"foldername"
del /s XXX_"*"
cls
exit

Answer 3

As Ron says, since the question is tagged "windows".

EDIT:

Ron's answer, which seems to have disappeared!, was to use del /s

EDIT2:

OK, it's valid only for file names, not for directories. For the directories you'd have to use something like sketched below.

Additional info: when you want to do the same thing recursively to files in a directory tree, and (unlike del ) there's no command that already does the traversing for you, you can use the /R option of the for command.

To see the for command's docs, do eg start "for-help" cmd /k for /? .

Cheers & hth.,
