Break a folder with many files to multiple subfolders (Windows 10)

Question

I have a folder with 110.000 files and I want a way to break this folder into multiple subfolders containing say 3000 files each (with a batch script perhaps?). (Trying a copy/paste with WinExplorer gets stuck in "Preparing to Copy".)

For example:

BigFolder
  |
NewFolder
|     |    |    |    |
Sub1  Sub2 Sub3 Sub4 Sub5...

I am surprised to find the same case of mine. I had 30,000 files that needed to be sorted, so I asked question on this page: Fast methods to copy(move) files in batch file

This is Compo 's script:

 @Echo Off If /I Not "%__CD__%"=="%~dp0" PushD "%~dp0" 2>Nul||Exit/B SetLocal EnableDelayedExpansion Set "DirN=-1" :Check_DirN Set/A "DirN+=1" If Exist "%DirN%" GoTo Check_DirN Set "limit=700" For %%A In (*.bat *.cmd *.txt) Do ( If Not Exist "%DirN%" MD "%DirN%" If /I Not "%%~nxA"=="%~nx0" RoboCopy . "%DirN%" "%%A" /MOV 1>NUL Set/A "limit-=1" If !limit! Lss 0 GoTo Check_DirN ) Echo(Task Done! Timeout -1 1>Nul 

And this is what I use and I edited for a bit for the purpose:

@Echo Off
If /I Not "%__CD__%"=="%~dp0" PushD "%~dp0" 2>Nul||Exit/B
taskkill /f /im explorer.exe >nul
taskkill /f /im SearchIndexer.exe >nul
sc stop WSearch >nul
sc config WSearch start= disabled >nul

SetLocal EnableDelayedExpansion
Set "DirN=-1"

:Check_DirN
Set/A "DirN+=1"
If Exist "%DirN%" GoTo Check_DirN
cls
echo Moving files to Directory %DirN%...
Set "limit=2999"
MD "%DirN%"
For %%A In (*.html) Do (
    RoboCopy . "%DirN%" "%%A" /MOV 1>NUL
    Set/A "limit-=1"
    If !limit! Lss 0 GoTo Check_DirN
)
Echo(Task Done!

start explorer.exe
start SearchIndexer.exe
sc config WSearch start= delayed-auto >nul
sc start WSearch >nul
Timeout -1 1>Nul

You can remove taskkill , start and sc part if desired. I added this part because explorer and Windows Search Indexer will cause waste of memory when moving files. I recommend you to run the script with Administrator privilege.

Try to test the script in small scale to see if it does work.
