Are doc and docx files usually the same? What is the difference?

Doc and docx are the same, both in Word text format, but there are still differences between them, as follows:

1, different versions

Doc is the document format used by Microsoft Office Word 2003, and docx is the document format used by Microsoft Office Word 2007.

2. Different sizes

The significant difference between doc and docx lies in the difference in size. Docx format is a zip file. We can use winrar to open docx files and get a bunch of files, similar to the source code of android programs or win7 desktop forms, in which we can find various configuration files, text files and media files.

3, the response speed is different

For example, many special effects can be modified only by modifying the configuration file, instead of repeatedly modifying large files like doc. Now docx has begun to replace doc format, but doc format is still dominant in many places. If you really want to open the docx format, you can use win7 Notepad. Docx format saves space quickly.

4. Different compatibility

Generally, the 2007 version (docx) can open the 2003 version file, but the 2003 version (doc) cannot open the 2007 version file, but the 2003 version can open the 2007 version file with the help of the compatibility package.
