I'm trying to find all files that have no extension in a Finder folder. I know how to search by extension and exclude a specific extension but what do I type in the box if I want no extension at all?

  • how can there be a file without extension (you mean it is not showing it?)

    @Buscar웃 not every file requires an extension. For example Brewfiles or shell scripts don't need an extension like .sh or so.

You can set up a Finder search like this:

- None of the following is true:
- - Filename contains .
- - Kind is Folder

The Finder does however exclude some system items from search results. The same search criteria produced 19'077 search results in Finder and 131'666 in HoudahSpot.

    Finer instructions for those who need it: In Finder after pressing ⌘F (Command-F) or typing in the search box, you'll get see search bar which has a + (Plus Sign) button on the far right. Click the + and a new bar of filter options will appear, with its own + button on the far right. On your keyboard, hold down the (Option key) and the + button will turn in to (Ellipsis) now press that! Then you can add the None and additional filters mentioned above.
