I have some file such as AAA_a001.jpg, BBB_a002.jpg, CCC_a003.jpg in Windows 7 and I'm trying to use batch to rename these file to a001_AAA.jpg, a002_BBB.jpg, a003_CCC.jpg.

Just to swap the content between _.

I have been searching for a while, but still don't know how to do this. Can anyone help? Thanks.

Use REN Command

Ren is for rename

ren ( where the file is located ) ( the new name )

example

ren C:\Users\&username%\Desktop\aaa.txt bbb.txt

it will change aaa.txt to bbb.txt

Your code will be :

ren (file located)AAA_a001.jpg a001.AAA.jpg
ren (file located)BBB_a002.jpg a002.BBB.jpg
ren (file located)CCC_a003.jpg a003.CCC.jpg

and so on

IT WILL NOT WORK IF THERE IS SPACES!

Hope it helps :D

@echo off
pushd "pathToYourFolder" || exit /b
for /f "eol=: delims=" %%F in ('dir /b /a-d *_*.jpg') do ( for /f "tokens=1* eol=_ delims=_" %%A in ("%%~nF") do ren "%%F" "%%~nB_%%A%%~xF"
)
popd

Note: The name is split at the first occurrence of _. If a file is named "part1_part2_part3.jpg", then it will be renamed to "part2_part3_part1.jpg"

as Itsproinc said, the REN command works!

but if your file path/name has spaces, use quotes " "

example:

ren C:\Users\&username%\Desktop\my file.txt not my file.txt

add " "

ren "C:\Users\&username%\Desktop\my file.txt" "not my file.txt"

hope it helps

I am assuming you know the length of the part before the _ and after the underscore, as well as the extension. If you don't it might be more complex than a simple substring.

cd C:\path\to\the\files
for /f %%a IN ('dir /b *.jpg') do (
set p=%a:~0,3%
set q=%a:~4,4%
set b=%p_%q.jpg
ren %a %b
)

I just came up with this script, and I did not test it. Check out this and that for more info.

IF you want to assume you don't know the positions of the _ and the lengths and the extension, I think you could do something with for loops to check the index of the _, then the last index of the ., wrap it in a goto thing and make it work. If you're willing to go through that trouble, I'd suggest you use WindowsPowerShell (or Cygwin) at least (for your own sake) or install a more advanced scripting language (think Python/Perl) you'll get more support either way.

I rename in code

echo off
setlocal EnableDelayedExpansion
for %%a in (*.txt) do ( REM echo %%a set x=%%a set mes=!x:~17,3! if !mes!==JAN ( set mes=01 ) if !mes!==ENE ( set mes=01 ) if !mes!==FEB ( set mes=02 ) if !mes!==MAR ( set mes=03 ) if !mes!==APR ( set mes=04 ) if !mes!==MAY ( set mes=05 ) if !mes!==JUN ( set mes=06 ) if !mes!==JUL ( set mes=07 ) if !mes!==AUG ( set mes=08 ) if !mes!==SEP ( set mes=09 ) if !mes!==OCT ( set mes=10 ) if !mes!==NOV ( set mes=11 ) if !mes!==DEC ( set mes=12 ) ren %%a !x:~20,4!!mes!!x:~15,2!.txt echo !x:~20,4!!mes!!x:~15,2!.txt
)

The PowerShell way works for me and easier to understand and change. However, got errors like rename-item : Source and destination path must be different until I changed it a bit. To rename files of the folder only:

dir | Where-Object {$.Name -match 'replaceMe'} | Rename-Item -NewName { $.Name -replace 'replaceMe','myNewText' }

To rename files of the folder and sub folders recursively:

Get-ChildItem -Recurse | Where-Object {$.Name -match '.Core.'} | Rename-Item -NewName { $.Name -replace '.Core.','.Framework.' }

You can try this one code:

echo off
cd D:\TEMP
for %%A IN (*.jpg) do ( call :dothings "%%A"
)
cd D:\2
goto :eof
:dothings
set A=%1
set P=%A:~1,12%
set Q=%A:~14,4%
set B="%Q% %P%.jpg"
ren %a% %b%
goto :eof

it will rename for example "Untitled-227 1965.jpg" to "1965 Untitled-227.jpg"

I found this solution via PowerShell :

dir | rename-item -NewName {$_.name -replace "replaceME","MyNewTxt"}

This will rename parts of all the files in the current folder.
