It appears Microsoft Word Autosave files have a different extension but have the same signature as doc:

SHA256: 3cccd0a5ab28b9652116321d2dafbfc3c582a2974d782f810a3bf05bc8e8acf8
File size: 27648

PhotoRec has recovered:

f0000000.doc - size=27648


WARNING: extension doesn't match - recovered file:doc - original: asd

Feel free to contact the developper if you think that PhotoRec should be able to recover this file. Don't forget to provide this URL.

Could this extension be added?

The asd file you provided is a fully functional Word file. Renamed it with a .doc extension and you will be able to read its content.
