Sharepoint Server error: This item cannot be deleted because it is still referenced by other pages

We might get this error when you try to delete from the _catalogsmasterpage directory.

Microsoft has provided a solution which doesn't look convincing at all : http://support.microsoft.com/kb/926812

We can use a different method:

• Open the Master gallery in Explorer view


• Create a Directory named "Delete"


• Cut all the un-wanted Master Pages and paste it inside the "Delete" directoty


• Delete the "Delete" Directory

And you got rid of all the unwanted pages .
