Folders-enabled SharePoint lists: Trigger a Flow only when Folders are modified
For organisational purposes or even for having different permissions in a SharePoint list, without having to handle item-level permissions, we can leverage folders in a list by enabling folders creation under the list advanced settings.
With folders in a list then we can break permissions in a folder instead of each item, and then grant access to a specific subset of list items in a SharePoint list.
When we create Power Automate flows based on SharePoint list item created or modified events (‘When an item is created’/’When an item is modified’), the Flow will be triggered by modifications/creation of items and also folders.
