doc is the older version of the Word document format. To improve file compatibility and avoid opening issues, they need to be uniformly converted to the newer docx format. If we have many doc files to convert to docx, we can use these 5 batch conversion methods: HeSoft Doc Batch Tool , WPS Office, ASPOSE online tool, LibreOffice command line, Word + folder save file.
Scenarios Requiring Batch Conversion of doc to docx
1. Unified Document Format
There are a large number of Word documents on the computer, some of which are legacy files in the older doc format. To standardize file formats and facilitate future archiving and long-term storage, it is necessary to unify these files into the docx format.
2. Improved Compatibility
docx is the new default format starting from Microsoft Office 2007, offering better compatibility in newer versions of Word and other office software. Older doc format files are prone to issues such as failure to open or formatting corruption. Converting them uniformly to the docx format effectively enhances file compatibility and prevents these problems.
3. Saving Storage Space
The docx format is based on compressed XML storage, whereas doc uses binary storage. For two files with identical content, the file size in doc format can be 1-2 times larger than in docx format. Batch converting doc files to docx format can save significant storage space.
4. Need for Long-Term Preservation
If we need to preserve Word documents for the long term, using the newer docx format can reduce issues caused by format obsolescence in the future.
