File Format Association
File Format Association helps you set which file types WPS Office opens by default and adjust related compatibility behavior. It provides the tools you need to manage file associations, compatibility modes, and default save formats more efficiently. With File Format Association, you can choose default opening for Word, Excel, PowerPoint, PDF, image, e-book, CAD, email, archive, mind map, and flowchart files, select compatibility with Microsoft Office 2003, 2007, or 2010, set new WPS Word, WPS Spreadsheet, and WPS Presentation files to save by default as .docx, .xlsx, and .pptx, and enable protection to keep associated file types from being changed by other programs. Whether you're standardizing document handling or maintaining compatibility settings, File Format Association helps you complete setup changes that take effect immediately after saving.
