What is a DOCX file?

The .DOCX file type refers to Microsoft word’s most recent file type. Beginning with the 2007 version of Word, Microsoft’s proprietary software for word processing, the word files are now saved with the .DOCX extension instead of the old .doc. This is in line with Microsoft’s approach to be compliant with the open XML standards.

The Docx files are very versatile and allow for a variety of formatting and other operations to be done on the Microsoft word files. The earlier DOC version used to store data in a single binary whereas the current DOCX version stores the data using the XML standards.

How to open DOCX files

If you cannot open the DOCX file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports DOCX among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the DOCX file can be found in the table. Now just download and install the appropriate application.

Possible problems with the DOCX format files

The inability to open and operate the DOCX file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Microsoft Word 2007/2010 Open XML Document Format file. Below is a list of possible problems.

  • Corruption of a DOCX file which is being opened
  • Incorrect links to the DOCX file in registry entries.
  • Accidental deletion of the description of the DOCX from the Windows registry
  • Incomplete installation of an application that supports the DOCX format
  • The DOCX file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the DOCX file.
  • Drivers of equipment used by the computer to open a DOCX file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the DOCX file should operate with your programs without any problem. If the problem with the DOCX file has not been solved, it may be due to the fact that in this case there is also another rare problem with the DOCX file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.DOCX) you have two ways to do it. The first and the easiest one is to right-click on the selected DOCX file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the DOCX file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Many files contain only simple text data. It is possible that while opening unknown files (e.g. DOCX) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
