I use Mystic Thumbs as an icon file viewer. I get great previews in my icon list for PDF files or Excel files. Can MysticThumbs help me with Word documents as well?
MysticThumbs is actually an image file viewer. It does have support for Excel and PDF files, but there is nothing said about the DOC files. You will have to contact the developer to request him to implement this feature as well or you could use the Plugins section on the official website to implement it yourself.
