Opening files app only shows “No file to preview”. No other buttons or options. How do you fix this?

Hello Gwartoy,

We want to help clarify what you are noticing.

From what we are seeing the iPhone can't recognize the file. Did it previously open?

Do files from the same source have the same issue?

If you download a new file does this occur?

What type of file are you trying to open?

View and modify files and folders in Files on iPhone - Apple Support using the articles here.

We hope this helps.

Cheers.
