Attachments control in Power Apps
A control that allows users to download files to their device, as well as upload and delete files from a list created using Microsoft Lists, or a Microsoft Dataverse table.
An Attachments control lets you open, add, and delete files from a list or a Dataverse table.
The attachment control has these limitations:
The attachment control only supports lists and Dataverse tables as the data sources.
Upload and delete functionality work only inside a form. The Attachment control appears disabled when in Edit mode and not inside a form. To save file additions and deletions, the app user must save the form. Because of this limitation, the Attachment control isn't available from the Insert tab but appears in the form when the Attachment form field is enabled in a SharePoint or Dataverse form.
Attachments control on a web browser lets you select multiple files, and allows use of drag and drop functionality. However, when using attachments control on Power Apps Mobile, you can only add files one at a time.
