Example configuration from the Zapier interface

The screenshot shows Number of files = 2, File1 and File2 mapped from previous steps (e.g., 2. File, 4. File), File Name1 = abc.docx, Sort Position1 = 1, Format Mode1 (dropdown). For each file, map File, File Name, and set Sort Position. Lower Sort Position = earlier in merge order.

If you see "File: (Exists but not shown)" and get errors, select the option that provides the full file content. See Zapier & Power Automate Tips for details.
