I want to do some thing simple (I thought...)

I've got something like this:


I just want to copy these Data with robocopy to a target (because I need a logfile and have to specify with attributes to copy).

But due to some limitations I can not copy the data in one run and have to split this Job (in real about 5000 Folders, 3TB).

So I want to specify the "starting folder" and the last folder like Folder00X (Folder001, +1, Folder100 ; the Job should start with Folder001 and with steps +1 it should copy the Folder002, Folder003....Folder100).


The job should start with Folder001, step +1, copy Folder002, ... Folder100

You can use a for /l loop in a batch file to do this.

The following batch file echoes the required list of folder names:

@echo off
setlocal enabledelayedexpansion
for /l %%i in (1,1,100) do (
   rem prefix the count with leading zeros
   set "_number=00%%i"
   rem extract the last 3 digits
   echo Folder!_number:~-3!


  • The batch file should be located in the directory one level above Folder001
  • Replace the echo command with a robocopy command that does the copy for you.
  • To process names with 4 digits (for example Folder1000, ... Folder 2000) you need to change the batch file.
    • Replace (1,1,100) with (1000,1,2000)
    • Replace "_number=00%%i" with "_number=000%%i"
    • Replace Folder!_number:~-3! with Folder!_number:~-4!


FOR /L %%parameter IN (start,step,end) DO command 


  • start : The first number
  • step : The amount by which to increment the sequence
  • end : The last number
