I need to batch rename my files, KHV!

Give me a program plz. :[ If it works on Vista I'll be a happy camper. Free would be super awesome. I've already tried two (one was called like Metamorphosis or something and the other was called Flexible Renamer) and they both kept closing (or not opening).

There's a lot of files (about 2500), they're pictures in BMP format. I want to be able to name them with a prefix and then numbers, like this:

thisismyprefix10203229832983.bmp

 

HOPE THIS HELPS

 

Rnaming all .bmp files at once

It could not get easier than this.

Code:

# Script RemaneBMP.txt
var str folder, prefix, list, file, newname
cd $folder
lf -n "*.bmp" $folder > $list
while ($list <> "")
do
    lex "1" $list > $file
    stex -p "^/^l[" $file > $newname
    set $newname = $prefix + $newname
    system rename ("\""+$file+"\"") ("\""+$newname+"\"")
done

This is in biterscripting ( http://www.biterscripting.com ). To try (first in a test folder), save the code in file "C:/Scripts/RenameBMP.txt", start biterscripting, enter the following command exactly as below.

Code:

script "C:/Scripts/RenameBMP.txt" folder("C:/Test") prefix("my prefix")

This will rename all .bmp files in folder "C:/Test" with prefix "my prefix".

Hope this helps.
