Batch script to delete certain files based upon one file (format vary sometimes) exist in all sub folders

To create a batch script that deletes certain files based on the existence of a specific file (with varying formats) in all subfolders, you can use a combination of for loops, conditional checks, and deletion commands (del). Here's a script that demonstrates this process:

Batch Script Explanation

The following script assumes you want to delete files (*.txt in this example) if a specific trigger file (trigger.txt in this example) exists in any subfolder. It recursively searches through all subfolders starting from the current directory.

@echo off setlocal enabledelayedexpansion rem Define the trigger file name (can vary) set "trigger_file=trigger.txt" rem Loop through all directories and subdirectories for /r %%d in (.) do ( rem Check if the trigger file exists in the current directory if exist "%%d\%trigger_file%" ( rem Display a message indicating the trigger file exists echo Trigger file found in "%%d" rem Loop through all files in the current directory for %%f in ("%%d\*.txt") do ( rem Delete the files matching the specified pattern (*.txt) echo Deleting "%%f" del "%%f" ) ) ) echo Done. pause

Script Breakdown:

  1. @echo off: Disables echoing of commands to the console, making the output cleaner.
  2. setlocal enabledelayedexpansion: Enables delayed expansion to handle variables within loops.
  3. set "trigger_file=trigger.txt": Defines the name of the trigger file that indicates which files to delete.
  4. for /r %%d in (.) do ...: Recursively iterates through all subdirectories (/r) starting from the current directory (.).
  5. if exist "%%d\%trigger_file%": Checks if the trigger file exists in the current directory (%%d).
  6. for %%f in ("%%d\*.txt") do ...: Iterates through all .txt files (*.txt) in the current directory (%%d).
  7. del "%%f": Deletes each .txt file found (%%f).

Notes:

  • Adjust trigger_file to match the actual filename pattern or format that might vary.
  • This script assumes you want to delete all .txt files found in directories containing trigger.txt. Modify *.txt to match the file pattern you want to delete.
  • Ensure you test this script in a safe environment before running it in a production setting, especially when using commands that delete files.

This batch script provides a basic framework to accomplish your task. Customize it further based on specific requirements or additional conditions for file deletion.

Examples

  1. Search Query: Batch script to delete files based on a specific file extension in all subfolders

    • Description: Deleting files with a specific file extension (.txt, .log, etc.) from all subdirectories using a batch script.
    • Code Example:
      @echo off for /r %%i in (*.txt) do ( del "%%i" echo Deleted file: "%%i" ) echo All .txt files deleted. pause

  2. Search Query: Batch script to delete files if a certain file exists in all subdirectories

    • Description: Deleting files if a specific marker file exists in all subfolders using a batch script.
    • Code Example:
      @echo off for /r %%i in (*) do ( if exist "%%~dpi\marker.txt" ( del "%%i" echo Deleted file: "%%i" ) ) echo Files deleted where marker.txt exists. pause

  3. Search Query: Batch script to delete files based on filename patterns in subfolders

    • Description: Deleting files based on specific filename patterns or wildcard matches in all subdirectories using a batch script.
    • Code Example:
      @echo off for /r %%i in (*pattern*.*) do ( del "%%i" echo Deleted file: "%%i" ) echo Files matching pattern deleted. pause

  4. Search Query: Batch script to delete files older than a certain date in subfolders

    • Description: Deleting files older than a specified date from all subdirectories using a batch script.
    • Code Example:
      @echo off forfiles /s /m *.* /d -30 /c "cmd /c del @path" echo Files older than 30 days deleted. pause

  5. Search Query: Batch script to delete empty directories after deleting files

    • Description: Deleting empty directories recursively after deleting files within them using a batch script.
    • Code Example:
      @echo off for /f "delims=" %%d in ('dir /ad /s /b ^| sort /r') do ( rd "%%d" echo Deleted directory: "%%d" ) echo Empty directories deleted. pause

  6. Search Query: Batch script to delete files of a specific size in all folders

    • Description: Deleting files larger than a certain size or within a specific size range from all directories using a batch script.
    • Code Example:
      @echo off for /r %%i in (*.*) do ( for %%F in ("%%i") do ( set size=%%~zF if %%size%% GTR 1000000 ( del "%%i" echo Deleted file: "%%i" ) ) ) echo Files larger than 1MB deleted. pause

  7. Search Query: Batch script to delete files based on file attributes in subdirectories

    • Description: Deleting files based on specific file attributes (read-only, hidden, system) from all subdirectories using a batch script.
    • Code Example:
      @echo off for /r %%i in (*) do ( attrib "%%i" | find "H" > nul && del "%%i" attrib "%%i" | find "S" > nul && del "%%i" attrib "%%i" | find "R" > nul && del "%%i" ) echo Files with specific attributes deleted. pause

  8. Search Query: Batch script to delete specific files based on a list of filenames in subfolders

    • Description: Deleting files matching specific filenames listed in a text file across all subdirectories using a batch script.
    • Code Example:
      @echo off set "listfile=list.txt" for /f "usebackq delims=" %%i in ("%listfile%") do ( for /r %%j in ("%%i") do ( del "%%j" echo Deleted file: "%%j" ) ) echo Files listed in list.txt deleted. pause

  9. Search Query: Batch script to delete files based on file creation date in all subdirectories

    • Description: Deleting files created before or after a specified date from all subdirectories using a batch script.
    • Code Example:
      @echo off set "cutoff_date=2023-01-01" for /r %%i in (*) do ( for /f "tokens=1-3 delims=/-" %%a in ("%%~ti") do ( set "file_date=%%c-%%a-%%b" if "%file_date%" LSS "%cutoff_date%" ( del "%%i" echo Deleted file: "%%i" ) ) ) echo Files created before %cutoff_date% deleted. pause

  10. Search Query: Batch script to delete files based on file size and type in subdirectories

    • Description: Deleting files of a specific type (.jpg, .pdf) and larger than a certain size from all subdirectories using a batch script.
    • Code Example:
      @echo off set "file_type=.pdf" set "min_size=1000000" for /r %%i in (*%file_type%) do ( for %%F in ("%%i") do ( set size=%%~zF if %%size%% GTR %min_size% ( del "%%i" echo Deleted file: "%%i" ) ) ) echo %file_type% files larger than %min_size% bytes deleted. pause
