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!
Find this file in all the web front end servers
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.
