File extension finding

Just finally switched to a new larger harddrive and didn’t install it myself.

I need to find my old dorico project files, but for the life of me, I can’t figure out how to get Windows file system to show me what the 3 letter extension on a Dorico project file in order to do a search.

It’s actually “.dorico” spelled out.

Thanks. I had no idea. So *.dorico should find every project file.
