The extension for Microsoft Word files is typically ".docx" for documents created in Word 2007 and later versions.

In older versions of Microsoft Word (prior to Word 2007), the default extension for Word documents was ".doc." However, with the introduction of Microsoft Office 2007, a new file format based on XML was introduced, and Word documents saved in this format use the .docx extension. This new format is more efficient and allows for better compatibility with other software and platforms.

So, to summarize:

  • Word files created in Word 2007 and later versions have the .docx extension.
  • Word files created in versions prior to Word 2007 may have the .doc extension.

It's worth noting that Word documents can also be saved in other formats, such as ".pdf" (Portable Document Format) or ".rtf" (Rich Text Format), depending on the user's preferences and intended use of the document.
