 * I noticed that the backup now has a .daf extension instead of .zip, and I can
   no longer extract the file. How can I extract .daf files on Windows?

 * Hi [@svweb](https://wordpress.org/support/users/svweb/),
 * Thanks for reaching out!
 * The `.daf` extension means DupArchive was selected as your archive engine in 
   Duplicator’s settings, that’s why your backup is no longer in `.zip` format.
 * If you’d prefer `.zip` backups, you can switch back by going to **Duplicator 
   > Settings > Backups > Archive Engine** and selecting **ZipArchive**. Future 
   backups will then be created in `.zip` format, which you can extract normally
   on Windows.
 * If you’d like to extract your existing `.daf` file instead, you can follow this
   guide on how to work with DupArchive files: [https://duplicator.com/knowledge-base/how-to-work-with-daf-files-and-the-duparchive-extraction-tool/](https://duplicator.com/knowledge-base/how-to-work-with-daf-files-and-the-duparchive-extraction-tool/)
 * Let us know if you run into any issues!

 * Thank you for the information, I switched back to zip, that’s indeed easier to
   extract on windows.
