Thanks for the response! That’s not quite what I meant, but I think I didn’t give enough context at first. When using an uploader, you have the option of marking files as private and attaching them to a thing:

This wouldn’t be a admin-created field called “Attached Files”, but it’s a built-in Bubble functionality.
When using this, I’m not seeing a way to list these files anywhere. [Thing’s] “attached files” isn’t an option when selecting a repeating group data source:

(I also tried this using “Uploaded File” as the Type of Content, but got the same result.)
I’m using Better Uploader to upload the files to Bubble, which also uses that “attach to” functionality. The problem is that I can’t find a way to reference files that are attached to a thing.
