Docx is a file format above above 2007. Due to the difference in format, word files in docx format cannot be opened before 2007. If the version before 2003 is considered, it will be saved in doc format with good compatibility. Even the old machine can be turned on normally. If you want to open docx files in Office2003, you must install the official docx patch to make office2003 support DOCX format files.
2. Different sizes
Docx format and doc format are both Word text formats, and the significant difference is the size difference. Docx format is actually a zip file. We can open docx files with winrar and get a bunch of files. Various configuration files, text files and media files can be found in docx files.
Its principle is equivalent to using two text documents, one for putting text information and the other for configuring format. In this way, two text files can achieve similar functions in doc format, so the volume is saved.
