Yep, SharePoint will not delete content when you remove a column from a list. It is still stored in the Database, that way you can do updates to columns without loss of data.

From: [email protected] [mailto:[email protected]] On Behalf Of Paul Noone Sent: Tuesday, 8 December 2009 11:25 AM To: ozMOSS Subject: Question about custom metadata Hi all, I recently had to perform a content type update on a number of large document libraries. In preparation for this I diligently created a view with all columns, opened it in Datasheet view and copied out the metadata for pasting back later. I then changed all documents to use the default Document content type; and deleted the custom content types and columns from the library. After updating and reactivating my CT feature I added them back to the list and then changed all documents to use the custom CT again. What I didn't expect to see was that all the custom metadata was still intact - and I'm not talking about Office Documents here. PDFs, images, emails, text files. You name it. Despite the wasted effort in trying to preserve this data I remain both very pleased and very confused by this revelation. Does anyone have any idea how this is possible?
