[Help] Batch File move every 15.000 files to another folders

Hi guys
I'm new here, please help

I have about 2 million email files that i want to convert into mbox files.
but the tool i used only can convert every 15.000 files.
so i need a batch file that can move this 2 million files into another folder (15.000 files each folder)
and the folder name is automatically created (counter).
example:

folder 1 contain 15.000 files
folder 2 contain next 15.000 files
.....
folder 134 contain the rest of files ...

note:
2.000.000 / 15.000 = 133,333 so there will be 134 folders

if can, i hope the files will be renamed too ... (adding ".eml")
example: file name 12345678.123456.abcde moved and renamed to 12345678.123456.abcde.eml

i already have the solution for linux, but i do not have any idea in windows

please help
and sorry for my english

thanks

Are you going to do this on a regular basis?

Do you want only 15,000 files in each folder or would you prefer to have all of the files in one folder?

Are the files currently in different folders?

I think you can just copy the files to a new location renaming them in the copy process
You have to use copy in Command Prompt, you cannot do this in Windows.

Try this as a test:
Make two new folders to test the process. They can be any name in any location, but I'll use C:\DirA_Src and C:\DirB_Dest as examples
Copy a few (20?) files that you want to rename to C:\DirA_Src folder. If the files have different extensions, that would be a good test.

Launch Command Prompt
Navigate to C:\DirA_Src and list the contents

cd C:\DirA_Src
dir

The try a rename with copy

copy *.* C:\DirB_Dest\*.*.eml

That might be difficult to decipher so I'll put the strings on separate lines
copy
*.*
C:\DirB_Dest\*.*.eml

The command has to be entered on one line, just know that there is a space between each string I show on separate lines. Also be aware that a space in the new folder names will require parenthesis around the folder name, so I recommend not having any spaces in the new folder names (note that I used the underscore character)

If that does what you want, then you can use the process to copy all of your files to any folder you choose.

Try it an let me know if it works or if you have other questions.

Hi Slartybart
renaming file was ok. thanks for your information.

About moving file,
It is not regular basis, i just want to do that if the email files > 1 million files.

example:
I have directory "c:\all" contains 2 million files
I want files in "c:\all" moved in new folder every 15.000 files

I need a batch files, so the result:

"c:\result\1" contain 15.000 files
"c:\result\2" contain next 15.000 files
etc

thanks

Hi Slartybart
Yes i want 15.000 files in each folder because the tool i use only can convert about 15.000 files in one process.
the idea is simple ... but i do not know how to implemented on windows batch ...
maybe i should mount the hdd into a linux computer and process there

:)

thanks

Hi Slartybart
The tool i used is Thunderbird add-on : Import email from maildir format into Mbox format.
I will going to use Linux's script then ... thanks for your help

It will be fun .. I was going to suggest Robocopy but that is more for fast copying of files.

Hmm .. will have to think on this one.
