[Constantine]

Hello @Yuri

Would you mind sharing a documentation on this preview feature? if I understand correctly, it differs from this topic:

Thumbnails in windows explorer

Does it work for docx +xlsx files in windows explorer? I mean thumbnaiIs as small pictures to identify the file without open it. I am used to this, is it possible? When saving a file, only the icon appears. thx a lot for advice Peter
