  1. Copy first ten jpg files in folder in alphanumerical order to new folder with out prior knowledge of jpg file names.
  2. Give each ten files in new location specific names like 'e100.jpg' - 'e110.jpg'.
  3. Powershell or batch script solution to run in windows enviroment.

Current research across related stack exchange posts:

  1. SO - Copy first N files from source directory to “serialized” destination directory using powershell

  2. SF - Copy first 10 files from a folder and subfolders

  3. SO - Powershell to pick random files from a folder and move them to another folder

  4. SU - How to batch copy rename files

  5. SU - How to optionally copy and rename a file in Windows?

  6. SU - PowerShell Script to Rename - Copy - Move

  7. Bulk renaming of files in PowerShell with sequential numeric suffixes

If I were to guess at a solution, based on the research as my coding skill are not very good, I think one of the solutions would look something like this:

Powershell

$excludealreadycopieditems = @()
$sourcefolder = "C:\SYS1"
$destinationFolder = "C:\SYS2"
$maxitems = 10
#Calculate how many folders should be created:
$folderstocreate = [math]::Ceiling((get-childitem $sourcefolder\*.jpg).count / $maxitems)
#Copy the items (if moving in stead of copy use Move-Item)
get-childitem $sourcefolder\*.jpg -Exclude $excludealreadycopieditems | sort-object name | select -First $maxitems | Copy-Item -Destination $destinationFolder$i ;
#Exclude the already copied items:
$excludealreadycopieditems = $excludealreadycopieditems + (get-childitem $destinationFolder$i\*.jpg | select -ExpandProperty name)
     }
ls *jpg | Foreach {$i=1} {Rename-Item _ -NewName ("$($.100){$:110#} .jpg" -f $i++) -whatif}

CMD

@ECHO OFF
SET SrcCount=0
SET SrcMax=10
FOR %F IN (C:\SYS1\*.jpg) DO IF !SrcCount! LSS %SrcMax% (
      SET /A SrcCount += 1
      ECHO !SrcCount! COPY %F C:\SYS2
      COPY %F C:\temp\output
      )
ren *.jpg e100.* e103.* e104.* e105.* e106.* e107.* e108.* e109.* e110.*
  • First ten is either e101.jpg..e110.jpg or e100.jpg..e109.jpg, otherwise I count eleven. Your cmd sample uses syntax !SrcCount! but doesn't enable delayed expansion with setlocal. – LotPings Mar 12 at 12:10
  • @LotsPing I made a mistake, yes the script I was looking for also required to start count from 0, which is why my sample was wrong (with 11), though don't want to change the question as it has already been answered well. – Under A Tree Mar 13 at 0:10

How can I copy 10 files to a new directory and rename them with a pattern?

Use the following batch file (test.cmd):

@echo off
setlocal EnableDelayedExpansion
set "source_dir=f:\test\jpg"
set "target_dir=f:\test\target"
for /f "tokens=*" %%f in ('dir /b %source_dir%\*.jpg') do (
  set /a "count+=1"
  set /a "target_count=!count!+100"
  copy "%source_dir%\%%f" "!target_dir!\e!target_count!.jpg" > nul
  if !count! EQU 10 goto :done
  )
rem finished
:done
endlocal

Notes:

  • Change source_dir and target_dir as appropriate

Example:

> dir jpg
 Volume in drive F is Expansion
 Volume Serial Number is 3656-BB63

So you did research a fair amount, but without evaluating your results it's not much worth.

In NTFS formatted drives an alphanumeric like sort is implied.

PowerShell:

Get-ChildItem -Path C:\Sys1 -Filter *.jpg -File |
  Sort-Object Name | Select-Object -First 10 |
    ForEach-Object -Begin {$i=100} -Process {
      Copy-Item -Path $_ -Destination (Join-Path "C:\Sys2" ("e{0:D3}{1}" -f $i++,$_.Extension)) -WhatIf
    }

If the output looks ok, remove the -WhatIf
