How do find all files without a name?

[NotNull]

But *with* a file extension (like .gif)?
(is it even possible to have a completely 'empty' file name?)

For a rough indication use:

file: wfn:.*

For an accurate result, use:

file: regex:^\.[^\.\s]*$

(not tested, though)

Idk, but there are quite a lot of files only with extension in my machine too. Mostly in Eclipse's Profile & metadata folders.

file: wfn:.*

Worked, Produced 2062 results (which includes some files like ".travis.yml")

file: regex:^\.[^\.\s]*$

Produced 793 results. Worked like a charm.

The last regular expression works correctly.

I meant filename.extension without "filename" AND without ".extension". Just a hypothetical situation ..

Oops. Sorry about that. I misunderstood.
