windows batch script to duplicate files in an image sequence

Question

I'm looking for a little help creating a batch rename script in windows

I have a folder of images, numbered sequentially by 3, ie.

• test_01.001.tif
• test_01.004.tif
• test_01.007.tif

and so on

What i'm aiming to do is copy and rename each one twice so that it makes up the missing images after it, to make up the full image sequence, so that

test_01.001.tif is copied twice and those copies renamed to:

test_01.002.tif and test_01.003.tif

And so on for the rest of the image sequence (goes up to 200)

Any help much appreciated, thanks!

Try this:

@echo off
setlocal EnableDelayedExpansion

for /F "tokens=1-3 delims=." %%a in ('dir /B /A-D *.*.tif') do (
   set /A new1=1%%b+1, new2=new1+1
   copy "%%a.%%b.%%c" "%%a.!new1:~1!.%%c"
   copy "%%a.%%b.%%c" "%%a.!new2:~1!.%%c"
)
