The Modular Disability Folder (MDF) is the official folder for paper cases. It promotes
            uniform assembly for all disability claims processing components within the Social
            Security Administration and the Disability Determination Services (DDS). For general
            information about using the MDF, see DI 70005.005.
         
         NOTE: Public contact personnel should not disclose disability claim determinations or decisions
            to a claimant or claimant representative until case processing is complete.
