What SharePoint library columns might be recognized as columns (details/fields) in File Explorer?

That would be amazing if that is possible. Being able to sync and change the meta data directly in file explorer or even filter/search by the meta data in windows would be huge. I am going to have a play with it and see whats possible. 

Note: if you right click on the column header Subject is already there, so maybe it just matches it up. Hmmm.
