Information about the .mdi (mdi) file type

Below is all the information we have available on file about the .mdi (mdi) file type.

.mdi
Microsoft Document Imaging image file.

Also known as an "MDI - Compressed Document Format" file.

This is a file generated as a result of printing to a "Microsoft Office Document Image Writer". This is a virtual printer which is installed with Microsoft Office (2003 and later). Printing to the Microsoft Office Document Image Writer (printer) will generate either a .mdi file or a .tiff file depending on how it is set-up.

The Microsoft Office Document Image Writer (printer) is an optional component of Microsoft Office.

The format of .mdi files is proprietary to Microsoft. However it is known that they contain a compressed image of the printed document and are based on the TIFF files. Microsoft Office should allow .mdi files to be opened and viewed.
