File uploads on a form
Updated Aug 31, 2026
A form field can accept a file upload — a headshot, a signed page, a certificate.
Where the file goes
The file is stored against the submission, not loose in your document library. Opening the submission is how you get to it.
Housekeeping
Attachments belonging to submissions that no longer exist are swept nightly, so a deleted submission does not leave its files behind.
