What are the steps to automate the conversion of .doc files to .docx files?

edit

There are a couple of ways to automate the conversion of .doc files to .docx files, but one possible way could be:

1. Identify the directory or folder where the .doc files are stored.
2. Create a script or program that can loop through all the .doc files in that directory.
3. Use a library or tool to convert each .doc file to .docx format. One option could be to use the Microsoft Word API or COM object to programmatically open and save each file in the newer format.
4. Save the new .docx files to a separate directory or folder, ideally with a similar file name or a way to identify which document they correspond to.
5. Test the script or program to ensure it is working as expected and all the files are converted correctly.
6. Schedule the script or program to run automatically, such as through a batch file or cron job, so that it can convert any new .doc files added to the directory or folder without manual intervention.
