Thanks for the reply,

I just ran thru the Folders table and I dont see any FolderID's that are identical, nore in the Files table.

I see relative paths that are the same from various module content copied into the respective portals. But as I see that should not be a problem..

Anything else I can do?

I see,

I cooked up a SQL query to locate such potential places : 

"SELECT t1.FolderPath, t1.FolderID, t1.PortalID, t2.FolderPath, t2.FolderID, t2.PortalID FROM dbo.Folders t1 INNER JOIN dbo.Folders t2 ON (t1.FolderID <> t2.FolderID) AND (t1.FolderPath = t2.FolderPath)"

This gives me several results where fx. "Containers\" is listed twice for the same portalID 0.

Do I dare alter the select to a delete statement? I ofcourse will backup the db before doing so, it's just a question if this is the right procedure.

Thank you for your help sofar.
