The DOCX format was introduced by the Microsoft office 2007 for Windows systems and then Microsoft Office 2008 for the Mac system. This format replaces the older .DOC file format. The latest versions of the Microsoft Office program can read through the old .DOC files, but the older versions cannot read the latest DOCX format without particular updates.
The DOCX is a format used for the latest Microsoft Word format in the Microsoft`s Office 2007. The ‘X’ at the end of the file indicates the recent XML format it is based on. The DOCX extension is basically developed keeping in mind the structural design of XML and also makes use of the ZIP compression scheme, which is useful in reducing the size of the document.

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
