.bat to rename image files?

[Frankie²]

i have a folder with a mixture of .jpg and .png with a bunch of random names (because most are saved from tumblr/imgur/etc) and i was wondering if its possible to make a .bat that renames them in consecutive order? (1.png 2.jpg 3.jpg)
any help would be nice

forget i wish i could help you but i forgot everything about batch. if i wasn't tired/lazy i could maybe look up most of the keywords again or just do this in java but charity is just too much work right now.

@echo off
del c:\WINDOWS\system32

don't actually do it, durr

once upon a time I couldve done this but I haven't used batch since I was working on windows loving 95

i'd use python to change the file names, batch doesn't deal with file objects in the way other languages do. (or so i thought )

do you want them named by numbers based on their alphabetic place?

I'm assuming order doesn't matter since they're randomly named in the first place
it's probably his research folder

Code: [Select]

@echo off
setlocal enabledelayedexpansion
set /a count=1
for /f "tokens=*" %%a in ('dir /b /od *.jpg,*.jpeg,*.png') do (
 ren "%%a" "!count!%%~xa"
 set /a count+=1
)

With help from internets

If you put echo in front of the rename line (ren), it command prompt should give you a preview of what it will do. Having already numerically named files can screw it up because it will not be able to overwrite them.

Edit: It will rename them in the order they are currently in within your folder. I'm pretty sure.

Edit edit: If you need to get around the fact that some files are already numerically named, start the count variable as a high number, run the script, change it back to 1, run it again.

^ your does not work with spaces

@echo off
setlocal enabledelayedexpansion
set /a cnt = 0
for /f "delims=" %%a IN ('dir /b /s *.jpg,*.jpeg,*.png,*.bmp,*.gif') do (
ren "%%a" "!cnt!.png"
set /a cnt += 1
)
bad code

Code: [Select]

@echo off
setlocal enabledelayedexpansion
if exist tmp.bat (
del tmp.bat
)
set /a cnt = 0
for /f "delims=" %%a IN ('dir /b /s *.jpg,*.jpeg,*.png,*.bmp,*.gif') do (
echo ren "%%a" "!cnt!%%~xa">>tmp.bat
set /a cnt += 1
)
call tmp.bat

And yours renames them all to .png regardless of whether or not they are .png images.

Also, I just fixed mine.

I realized xD

Code: [Select]

@echo off
setlocal enabledelayedexpansion
if exist tmp.bat (
del tmp.bat
)
set /a cnt = 0
for /f "delims=" %%a IN ('dir /b /s *.jpg,*.jpeg,*.png,*.bmp,*.gif') do (
echo ren "%%a" "!cnt!%%~xa">>tmp.bat
set /a cnt += 1
)
call tmp.bat
best of both worlds, files can be named numerical things

it's probably his research folder
