I am using sp2010. I have a document library. In this library we have many folders. Inside these folders we have items. When I see the list of items in a folder I would like to have a column with the parent folder name. Is this possible?
No OOTB way but You can add a column on the document library and populate it with the document parent folder name using Event handler ItemAdding / ItemAdded event.
Here is method how to create event handler.
