Search for an attached file

This may super easy to do but I can’t seem to find how to do it. Once a file has been uploaded as a private attached file. How can I search for it?

I attached a picture to a thing using the file uploader with option “Make this file private”. But then, when searching for that thing elsewhere, I don’t have the option for “This things’s attached file”.

Can someone help?

Did you ever solve this?
Seems strange that type of content can be set to file, but not data source.

Hey @simon7, unfortunately I haven’t found a way. I didn’t spend much time on the issue either…
