Split folder contents into subfolders containing 200 items per folder

Hi. I'm a musician and I've run into a slight problem that may be solvable via windows 10. This morning I booted up my copy of Ableton Live and opened up a copy of Remidi 2 as a VST plugin. This probably seems irrelevant but I'm just putting things into context. I loaded up some midi files and off I went. However, I went to a directory containing midi files and Ableton live locked up. After several hours of faffing around I worked out that Remidi 2 was struggling to cope with the 169 thousand plus files in the directory that I was using. So I spent an hour or 2 breaking the files into folders 0 to 10 and a to Z thinking this may sort it. However, as some of the folders still contain 5000+ files Remidi is still struggling to read them so I was wondering if there was a way in Windows 10 to batch create a number of folders and move say 200 to 250 files to each subfolder. I did a lot of googling hoping I could find some form of software to do this and then it occurred to me that this may be possible in windows 10 somehow. Any ideas?
I'm using windows 10 home version 10.0.19042 Build 19042

You could probabaly use a batch file to create the folders and move say 500 files into each.

I havent tested this but looks like it would work. Change 500 to how many files you want in each folder, and change .mp4 to whatever extension your music files have. Copy and paste the code into a text file file and save it as copyfiles.cmd

Code:

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set fileCount=500
set filesNow=0
set nameStart=000
set nameEnd=000
FOR /F "usebackq delims=" %%i IN (`dir /b *.mp4`) do (
    set /a filesNow+=1
    set /a tmpValue=filesNow %% fileCount
    if "!tmpValue!"=="1" (
        set "nameStart=%%~ni"
        mkdir _tmpDir_
    )
    move %%~nxi _tmpDir_\
    if "!tmpValue!"=="0" (
        rename _tmpDir_ !nameStart!-%%~ni
    )
    set "nameEnd=%%~ni"
)

if exist _tmpDir_ rename _tmpDir_ %nameStart%-%nameEnd%

That will be easier.

I used the folder axe program after a few false starts. The official download page only seems to have corrupted versions of the files but I found it somewhere and it's great. Does everything I wanted it to.

I was interested in the batch idea too but, looking at the code, couldn't see where it would ask for the directory to work and directories created. Then again though, I've only used BAT programs infrequently so don't really understand the lingo. Thanks everyone for your help. I'm off to split hundreds of thousands of files into batches of 200 now

So far I've only managed to find a corrupted version of folder access if someone could perhaps let me know if they have one I'd be happy to provide my email address or figure something out. Thank you very much, Peter

I just searched for folder axe in my web history and it looks like I got it from a site called Lo4D.com . If this doesn't work, just post again and I'll look a bit more deeply. Failing that I'll see if I can find the original download.

Thank you , I got version 7 I found. Appreciate your help!!!!!!
