If we accidently deleted the default.aspx and List view pages from SharePoint sites, SharePoint 2007 doesn’t provides the option to restore those pages. We have to manually create or reset the site to “site definition” to restore those pages.
But SharePoint 2010 provides the option to restore the default.aspx and List/Library view pages. After deletion , the pages are moved to recyle bin. By using recycle bin, we can restore those pages to the Site.
