Some Microsoft related file types (docx, emz and mdi)

The MDI file type is mainly related with 'Office' by Microsoft Corporation. The MDI is a a high resolution, tag-based graphics format. MDI files are only supported by the Microsoft Office 2003 version of Microsoft Office Document Imaging. Microsoft Office Document Imaging uses Microsoft Document Imaging Format (MDI), a file format based on the Tagged Image File Format (TIFF) that is designed to store images by page layout. Both formats (MDI and TIFF) are capable of storing text recognized by optical character recognition (OCR) along with images and using this OCR may be turned into a Word (.DOC) document.
In general, images that are saved in the MDI file format take up less disk space than the same images saved as TIFF files. The image quality of an image saved in the MDI file format is comparable to that of the same image saved in TIFF.

The DOCX file type is also mainly related with 'Word' by Microsoft Corporation. This is the new format for Microsoft Office documents (2007). It is a combination of XML architecture and ZIP compression for size reduction. It's a completely open standards based file format; contains document text, images, formatting, styles, drawn objects, and other document settings; commonly used to author documents in business and academic settings.
Changing docx documents into other formats is very easy if you know how, or have the correct docx converter software. Converting docx to the older doc format used by Microsoft Word or to Adobe’s pdf format is possible, offering better compatibility with partners and colleagues. DOCX files are designed to make document contents accessible; for example, document text is saved using plain text files and document images are saved as individual image files within the DOCX file.
Docx isn’t just qualified to use on a Windows based computer, other operating systems such as Linux and Mac OS X also include software or filters allowing users to share information thru the docx Office Open XML format.

Compressed image file used by Microsoft programs such as Visio and the Office suite; contains an Enhanced Metafile (.EMF file) that has been compressed with the .GZIP compression algorithm. The EMF file type is a type of image file incorporating a recorded sequence of Windows GDI (Graphics Device Interface) graphics functions and is the successor to the older WMF (Windows Metafile) format. The GDI is a set of functions for Windows programmers that supplies basic drawing functionality, and anything that can be drawn with the GDI functions can be saved to an EMF file with very little attempt.
EMZ files are simply EMF files that have been compressed using the extremely common GZIP type compression and so they can simply be decompressed prior to viewing by any compression/archive software package with support for GZIP. For example, changing the extension to .GZ will often enable you to use software such as WinZip or WinRar to extract the EMF files. Sometimes the files holded in the EMZ might have their extension replaced to EM upon extraction. In these cases, adding the missing F on to the file extension is all that is needed to open the files.
