I am working on a Power Automate solution to mirror the contents of a network drive (using the File System connector via on-premises data gateway) into a SharePoint document library.
The folder I want to sync (X:\TEST) contains multiple levels of subfolders, and the depth of the folder structure can increase in the future (currently about 5-6 levels).
My current flow uses the File System → List files in folder → loop through items → conditionally create folders and upload files to SharePoint. This works for one level, but I want to make it recursive to handle any future folder depth dynamically, without manually duplicating the “List files” and “Apply to each” actions for each subfolder level.
I tried using a child flow that calls itself recursively (Run a Child Flow → same child flow), but Power Automate gives an error saying the child flow must end with a response action.
My key question
Is there a Power Automate-supported way to create a recursive flow (parent → child or self-recursive) for dynamically traversing unknown folder depths?
Or is the only solution to manually repeat the folder listing logic a fixed number of times?
Are there better ways to achieve this within Power Automate ?
Appreciate any best practices or examples from anyone who has solved a similar problem.
Thanks in advance!
This is the current outline of my Parent and Child flows.
