Attachments and document library forms

Understand the difference between SharePoint list attachments, form libraries, and document-library metadata forms.

Quick answer

In short

Attachments and document-library forms need validation because SharePoint list attachment behavior differs from InfoPath form libraries and document metadata libraries.

Most likely cause

An InfoPath form library stored XML documents, while a Power Apps form usually edits list or library metadata. Those are not identical storage patterns.

What to do next

Confirm whether the replacement app should edit a list item, a document library item, or a related document set before relying on the generated save behavior.

Storage patterns

  • SharePoint list with attachments: one item plus attached files.
  • Document library metadata form: one file plus metadata columns.
  • InfoPath form library: XML documents created from a template.
  • Related document library: files are stored separately and linked to the parent record.

Generated app expectations

A generated .msapp can connect to the configured SharePoint list or library, but document-creation behavior, template XML submit, and attachment lifecycle may need additional Power Apps or Power Automate work.

Validation checklist

  1. Create a new record with a test attachment or document.
  2. Edit the record and confirm existing attachment/document behavior.
  3. Check library metadata columns after submit.
  4. Confirm users can open the saved file or record from SharePoint.
