What is a docx file?

A DOCX file is the default document format for Microsoft Word, using an XML-based structure to store text, formatting, images, and other content. It replaced the older DOC format starting with Microsoft Office 2007 and is now the standard for word processing across most platforms. DOCX files are compressed, widely compatible, and can be opened by Microsoft Word, Google Docs, LibreOffice, and many other applications.

File management is the practice of storing, organizing, locating, and distributing digital files.

How to open it

The DOCX is a smaller document file format than the DOC, making it convenient to send via email and store on a hard drive. The DOCX is a compressed file, meaning it’s shrunken in size to reduce its impact on storage space. A DOCX is opened either using Microsoft Word or alternative, third-party programs.

It’s one of the most popular document file types, which is convenient when sharing with others. In fact, most users have Microsoft Word and can easily open and edit the file. In a team setting, a DOCX is ideal due to its editing capabilities. Team members can quickly share and edit the DOCX amongst one another, making it perfect for projects and campaigns.

When to use a different document file

Articles, newsletters and advertisements are best created using DOCX.  A DOCX is used to create resumes and cover letters, though it’s not ideal because of how easy it is to edit a DOCX. In these instances, consider a different file format, especially for professional documents such as cover letters or resumes. A format such as a PDF document file is better in this instance because it’s harder to accidentally edit or change.

To convert a DOCX file:

  1. Open the file in Microsoft Word
  2. Click ‘file’
  3. Click ‘save as’
  4. From the dropdown menu, select the file type you wish to save it to (PDF, etc)

Alternatively, if you prefer to let a converter program handle the conversion process, those are widely available. Zamzar’s browser-based system has an easy-to-use interface and doesn’t require installation of a program to use. Give it a shot if you have multiple files to convert, as it might save you time.

Consider the ways in which a DOCX benefits different companies and teams. As tech progressed, Microsoft changed the way its document file type construction. Look for future similar developments to bolster potential.
