Is it possible to rename assets folder? If possible which files do i need to modify?
Yes, sure, of course, you need adapt references to that folder accordingly.
Which files contains references of assets folder? I will update my own files. i want to know the list of kirby files.
Kirby doesn’t use the assets folder internally. It’s purely for frontend stuff.

In that case you have to change the root folder and URL, see docs:
