How to change Folder Icon in all Document Library

how could I change the Folder Icon in Sharepoint? Is something programmatically, on CSS or simply to change icon in the specific image folder?

Thank you very much!

Answer 1

Find this file in all the web front end servers C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\IMAGES\itdl.png

Replace this with your own image and your folder icon will get updated.

Please note this will effect at a farm level , so if you want to make it site collection specific , you need to use visual studio and create a custom feature to establish the same.
