There was a Sharepoint 2007 site that was maintained without touching the code. People had their masterpage set by using links in the UI, SiteActions>>(under Look & Feel)MasterPage selecting default.master.
Now, they need some changes in the masterpage.
When I opened the site in Sharepoint designer 2007, the masterpage was referenced as MasterPageFile="~masterurl/default.master".
I want to open this master page which they refer to ~masterurl/default.master.
I have checked every .master inside the _catalogs folder but nothing is fruitful.
My task is to identify the masterpage they have used & to modify it.
Help me loacte the master page ~masterurl/default.master
