I have an extremely large database and most of the space is the index size. I moved several indexes to a different file group (just to experiment) but no matter what I do I cannot reduce the size of the MDF. I tried shrink database, shrink files, rebuilding clustered index. What can I do to reclaim that space in the MDF? I've moved 15GB worth of indexes to a different file group. Is it even possible to reduce my mdf by that same 15gb (or close to it)?
