How to rename files in folders to foldername using batch file

Question

Could any of you help me with a problem I have with a lot of files with the same name, placed in sperate folders.
The folders are named with numbers, but the files inside are named index.XXXX - where XXXX could be .jpg or .html or .pdf.
I would like to make a 'program' that can rename all the 'index' files to the same name as the folder they are placed in.
The folders are named with 6 digit numbers - all different.
After this hopefully has been done, then I would like to move all the renamed files to a new single folder, so it will be easier for me to see the whole content.
Looking forward to reading your answers.

Tested folder structure:

C:\Users\Administrador\Desktop\Nueva carpeta (3)\123321
C:\Users\Administrador\Desktop\Nueva carpeta (3)\123321\Index.txt

C:\Users\Administrador\Desktop\Nueva carpeta (3)\123456
C:\Users\Administrador\Desktop\Nueva carpeta (3)\123456\Index.php

C:\Users\Administrador\Desktop\Nueva carpeta (3)\123456\000000
C:\Users\Administrador\Desktop\Nueva carpeta (3)\123456\000000\Index.css

C:\Users\Administrador\Desktop\Nueva carpeta (3)\654321
C:\Users\Administrador\Desktop\Nueva carpeta (3)\654321\Index.html

C:\Users\Administrador\Desktop\Nueva carpeta (3)\654321\666999
C:\Users\Administrador\Desktop\Nueva carpeta (3)\654321\666999\Index.jpg

Output:

Ren: ".\123321\Index.txt"      "123321.txt"
Ren: ".\123456\Index.php"      "123456.php"
Ren: ".\654321\Index.html"     "654321.html"
Ren: ".\000000\Index.css"      "000000.css"
Ren: ".\666999\Index.jpg"      "666999.jpg"

If you want a GUI to do all the above, Use Bulk File Rename.

Open it up, Browse to your folder. Now check the Sub Folders option in the Selections tab. All your files under the folders will be listed. Select the files in the browser.

In the File tab switch the first option from Keep to Remove. Then go to the Append Folder Name tab and set option Prefix for property Name. Click on Rename to complete.

The advantage with this is that it shows you a preview of what your files will be renamed to.
