I have a directory structure as below:

Folder

  > SubFolder1

    > FileName1.abc

    > Filename2.abc

    > .............



  > SubFolder2

    > FileName11.abc

    > Filename12.abc

    > ..............



  > ..........

etc. I want to rename the files inside the subfolders as:

SubFolder1_Filename1.abc

SubFolder1_Filename2.abc

SubFolder2_Filename11.abc

SubFolder2_Filename12.abc

i.e. add the folder name at the beginning of the file name with the delimiter "_". The directory structure should remain unchanged. Note: Beginning of file name is same. e.g. in above case File*.

I made below Script

for /r "PATH" %%G in (.) do (

  pushd %%G

  for %%* in (.) do  set MyDir=%%~n* 

  FOR %%v IN (File*.*) DO REN %%v  "%MyDir%_%%v" 

  popd

  ) 

Problem with the above script is that it is taking only one Subfolder name and placing it to the beginning of file name irrespective of the folder.

You can do this in a more user friendly way using ReNamer, with a single renaming rule:

1. Insert ":File_FolderName:_" as Prefix (skip extension)

You can also save it as a Preset and use it for command line renaming.

To rename only files in the immediate child folders

@echo off

pushd "Folder"

for /d %%D in (*) do (

  for %%F in ("%%~D*") do (

    for %%P in ("%%F..") do (

      ren "%%F" "%%~nxP_%%~nxF"

    )

  )

)

popd

To recursively rename all files in child folders

@echo off

pushd "Folder"

for /d %%D in (*) do (

  pushd "%%D"

  for /r %%F in (*) do (

    for %%P in ("%%F..") do (

      ren "%%F" "%%~nxP_%%~nxF"

    )

  )

  popd

)

popd

Make sure you only run either script once! You don't want to put multiple prefixes in front of the files :-)

Additional code could be added to make it safe to run multiple times.

If you want to rename files inside subfolder only this is the solution.

for %%f in (.) do set "A=%%~dpnxf"

for /r "%A%" %%f in (.) do call :func "%%~f"

goto :EOF

:func

set "B=%~1"

for %%g in ("%B%") do set "C=%%~dpnxg"

for %%g in ("%C%") do set "D=%%~nxg"

cd  %C%

set "k=%C%"

if NOT %A%==%k% FOR %%v IN (*.*) DO REN "%%v" "%D%_%%v" 

goto :EOF

You could do it easily by using Windows Powershell. That's a two-line script to rename all files in subfolders the way the file name gets a subfolder name prefix.
Consider this simple structure in Drive D:

D:folder1Sub1

         Sub1 - AAAA.txt

          Sub1 - BBBB.txt

           Sub1 - CCC.txt

D:folder1Sub2

          0 AAAAA.txt

          0 CCCC.txt

Here is the script:

PS C:UsersUser> cd D:folder1

PS D:folder1> get-childitem -recurse | Rename-Item -NewName {$.Directory.Name + " - " + $.Name}

By running the script all files will be renamed with directory name prefix.
