How to create batch file that move files from sub-folder up one level renaming duplicates?

问题

I already have a batch file that I can drop in any SHOW_NAME directory and it will move files from a sub-folder to its SEASON parent directory. For example:

F:\TV_SHOWS\SHOW_NAME\SEASON1\TITLE_EP1\title_episode1.mkv
F:\TV_SHOWS\SHOW_NAME\SEASON1\TITLE_EP2\title_episode2.mkv
F:\TV_SHOWS\SHOW_NAME\SEASON1\TITLE_EP3\title_episode3.mkv
F:\TV_SHOWS\SHOW_NAME\SEASON1\title_episode3.mkv

When it moves all files to the parent folder (SEASON1) the "title_episode3.mkv" is a duplicate and overwrites the original. How can I automatically rename by appending a number "title_episode3 (1).mkv"?

Here is the code that I use in a batch file:

@echo off
for /d /r %%f in (*) do (
for /d %%g in ("%%f\*") do (
   for %%h in ("%%~g\*.mkv") do move "%%~h" "%%~f" >nul 2>&1
    )
)

Thanks!

This commented batch file can be used for this task:

@echo off
setlocal EnableExtensions DisableDelayedExpansion

rem Search for any file two directory levels below specified directory
rem and pass to subroutine MoveFile the name of the file with full path.

for /D %%A in ("F:\TV_SHOWS\SHOW_NAME\*") do (
    for /D %%B in ("%%A\*") do (
       for /F "delims=" %%I in ('dir "%%B\*" /A-D /B /S 2^>nul') do call :MoveFile "%%I"
    )
)

endlocal
goto :EOF

:MoveFile
set "FilePath=%~dp1"
set "FileNameOnly=%~n1"
set "FileNameFull=%~1"
set "FileName+Ext=%~nx1"
set "FileExtension=%~x1"

rem For files staring with a dot and not containing one more dot.
if "%FileNameOnly%" == "" set "FileNameOnly=%~x1" & set "FileExtension="

rem Get path to parent folder ending with a backslash.
for /F "delims=" %%J in ("%FilePath:~0,-1%") do set "FileParent=%%~dpJ"

rem Uncomment the line below to see the values of the six File* variables.
rem set File & echo/

rem Does a file with current file name not exist in parent folder?
if not exist "%FileParent%%FileName+Ext%" (
    rem Move the file to parent folder and if this was successful
    rem delete the folder of the moved file if being empty now.
    move "%FileNameFull%" "%FileParent%%FileName+Ext%" >nul
    if not errorlevel 1 rd "%FilePath%" 2>nul
    goto :EOF
)

set "FileNumber=1"
:NextFile
if exist "%FileParent%%FileNameOnly% (%FileNumber%)%FileExtension%" set /A "FileNumber+=1" & goto NextFile

move "%FileNameFull%" "%FileParent%%FileNameOnly% (%FileNumber%)%FileExtension%" >nul
if not errorlevel 1 rd "%FilePath%" 2>nul
goto :EOF

Running the batch file a second time on same directory with no new subdirectory and no new file does not change anything.

For understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully.

call /?
echo /?
endlocal /?
for /?
goto /?
if /?
move /?
rd /?
rem /?
set /?
setlocal /?
