where are button files held?

Hi People.

Please can someone point me at where I will find the button files?

I have a site which is blue as the theme and I would like to edit the buttons to reflect my site.

Found it

Anyone else looking later for this answer, well you will find them here.
/components/com_joobb/assets/templates/joobb/themes/joobb_black

However, I cannot edit them? I cannot change the name via FTP, everything says Access Denied? Any ideas?

Is there no help here?

It's been 24 hours since my message. Has nobody got a solution to my problem?

I am trying to alter the buttons but I can't get in to change the files. It's write protected and can't change them. Any ideas please?
