Difference Between DOC and DOCX (With Table)

DOC vs DOCX

DOC AND DOCX are file formats used in Microsoft’s Word application. The DOC format came in as soon as the Microsoft word was first released and was used till 2003 version of word. DOCX came in 2007 and is a newer format.

The difference between DOC and DOCX format is that the storage of a document in DOC is done in a binary file that contains all the related formatting information whereas the storage of a document in DOCX is done in a zip file that also contains all the XML files related to the document.

Though DOCX is a newer format, users can still use the DOC format if they wish to do so. One of the biggest problems that the DOCX format faces is that it is not compatible with Word 2003 and other older versions of it. This means that if you try to open a DOCX format file in any of the older versions, it will not open.

This can cause problems in sharing documents among people as not everyone updates their software every now and then with the newer versions. But this problem was solved as Microsoft released a compatibility pack which allows the older versions of Word to open the DOCX format.
