Have you ever searched your Gmail thinking,
“I know it was a PDF invoice, but where did it go?”
You remember the client’s name, but not the subject line or the date.
This literally happened to me just now.
I was looking for an invoice, with no clear memory of when it was sent.
What saved me was this simple search:
filename:pdf client-name
It worked instantly.

Gmail search isn’t weak.
In my case, I simply didn’t know how to use it properly.
In this article, I’ll show you how to search Gmail by file type,
using practical examples like PDFs, Excel files, and ZIP archives.
