This file is saved in a binary format, which requires a specific program to read its contents.


High-resolution, tag-based graphics format developed from the TIFF format; used by Microsoft Office for saving scanned documents; may be turned into a Word (.DOC) document using OCR (optical character recognition) software.

More Information

MDI files are created and opened with Microsoft Office Document Imaging (MODI), which is included with Office XP, 2003, and 2007.

NOTE: Microsoft stopped including MODI with Office 2010, so you cannot open MDI files in Office 2010. Saving documents created with MODI in the .TIF format allows for better compatibility with other programs.
