Batch File - Recursively check folders and move files - batch-file

Question

I am trying to create a windows batch file that will scan a folder with many sub folders. Each sub folder can contain many files. I need the script to check if a sub folder contains over a certain number of files, and if it does move half of the files to a new folder with the same name but with a number at the end.
Example:
Main folder
-Subfolderone
-Subfoldertwo
-Subfolderthree
If Subfoldertwo contains over a certain number of files, lets say 1000, then half of the files within Subfoldertwo will be moved to Subfoldertwo(2), and so on for each sub folder.
Main folder
-Subfolderone
-Subfoldertwo
-Subfoldertwo(2)
-Subfolderthree
Any help would be much appreciated. Thank you.

Answer 1

#ECHO OFF
SETLOCAL
SET "sourcedir=c:\sourcedir"
SET limit=5
FOR /f "delims=" %%a IN ('dir /b /s /ad "%sourcedir%\*"') DO (
SET /a newnum=2
FOR /f %%c IN ('dir /b/a-d "%%~a" 2^>nul ^|find /c /v ""') DO IF %%c gtr %limit% CALL :process "%%a"
)
)
GOTO :EOF
:process
IF EXIST "%~1(%newnum%)\" SET /a newnum+=1&GOTO process
ECHO MD "%~1(%newnum%)"
FOR /f "skip=%limit%delims=" %%m IN ('dir /b /a-d "%~1"') DO ECHO MOVE "%~1\%%m" "%~1(%newnum%)\"
GOTO :eof
Simple enough. I've set the sourcedir to a constant for my testing and the limit to 5 for the same reason.
First build a list of the original diretory tree, then count the files in each directory. If that count is greater than the limit, process the directory.
In process, first find whether the proposed new directory already exists. If it does, keep incrementing the number 'til it doesn't.
Then list the filenames (only) from the original full-directoryname, skipping the first %limit% and for the remainder, move them to the new directoryname.
The required commands are merely ECHOed for testing purposes. After you've verified that the commands are correct, change ECHO MD to MD to actually create the directories. Append 2>nul to suppress error messages (eg. when the directory already exists)
AND change ECHO MOVE to MOVE to actually move the files. Append >nul to suppress report messages (eg. 1 file moved)
Edit : revised for 'move half the files'
#ECHO OFF
SETLOCAL
SET "sourcedir=c:\sourcedir"
SET limit=5
FOR /f "delims=" %%a IN ('dir /b /s /ad "%sourcedir%\*"') DO (
SET /a newnum=2
FOR /f %%c IN ('dir /b/a-d "%%~a" 2^>nul ^|find /c /v ""') DO IF %%c gtr %limit% SET /a nmove=%%c / 2&CALL :process "%%a"
)
)
GOTO :EOF
:process
IF EXIST "%~1(%newnum%)\" SET /a newnum+=1&GOTO process
ECHO MD "%~1(%newnum%)"
FOR /f "skip=%nmove%delims=" %%m IN ('dir /b /a-d "%~1"') DO ECHO MOVE "%~1\%%m" "%~1(%newnum%)\"
GOTO :eof
(simply calculate half of the count into nmove then skip that number instead)

Answer 2

you might test this:
#ECHO OFF &SETLOCAL
set "StartFolder=X:\Main folder"
set /a MaxFiles=1000
cd /d "%StartFolder%"
:NewFolderCreated
set "NewFolderFlag="
for /f "delims=" %%a in ('dir /b /ad /on') do call:process "%StartFolder%\%%~a"
if defined NewFolderFlag (goto:NewFolderCreated) else goto:eof
:process
SETLOCAL
cd "%~1"
for /f %%b in ('dir /b /a-d 2^>nul^|find /c /v ""') do set /a FileCount=%%b
if %FileCount% leq %MaxFiles% exit /b
set /a MoveCount=FileCount-MaxFiles
set "CurrentFolder=%~n1"
set "NextPath=%StartFolder%\%CurrentFolder%(2)%~X1"
echo("%CurrentFolder%"|findstr /re ".*([0-9][0-9]*)\"^">nul||goto:moving
set "BasePath=%CurrentFolder:~0,-1%"
:loop
if not "%BasePath:~-1%"=="(" set "FolderNo=%BasePath:~-1%%FolderNo%"&set "BasePath=%BasePath:~0,-1%"&goto:loop
set /a FolderNo+=1
set "NextPath=%StartFolder%\%BasePath%%FolderNo%)%~X1"
:moving
echo(Moving %MoveCount% files from "%~1" to "%NextPath%".
md "%NextPath%" 2>nul &&set "NewFolderFlag=true"
for /f "skip=%MaxFiles%delims=" %%b in ('dir /b /a-d /o-n') do move "%~1\%%~b" "%NextPath%" >nul
endlocal &set "NewFolderFlag=%NewFolderFlag%"
exit /b
