Files in Power Apps – Knowledge Reminder

Power Apps does not have ready-made solutions for handling files. The standard form allows us to add a file as an attachment to a SharePoint list. To transfer the file from the list attachments to the document library, we need to use Power Automate.

If we create a new or copy an existing file in a SharePoint document library, we also need to use Power Automate

CCurrently, Power Automate is the primary tool that allows us to perform file operations in Power Apps

PPower Automate gives us two options: using standard functions for a given connector or calling SharePoint REST API

What and how we test?

  1. Create a copy of the file using the SharePoint REST API
  2. File Copy Using Power Automate #1
  3. File Copy Using Power Automate #2
  1. I use a specially prepared application for tests
  2. Each operation is performed 10 times and the average of 10 measurements is taken as the result
  3. The procedure is repeated for different file sizes
We do not test the operation of uploading the file to the library to avoid the impact of network speed on the test. We only check server-side operations.

Test application

1After selecting the file, the application places the file in the SharePoint library using the SharePoint REST API


2Then it repeats the procedure for creating a copy of the file with the Power Automate function 10 times: Get ContentCreate File and Copy file
