For your Recurrence trigger you can reduce the concurrent runs so that your Azure Storage File connector isn't hitting that limit. Since you have 6, I would consider starting with 3 and see if that helps your issue.
I don't know enough about what the parallel branches are doing, but would it be possible to place them in a foreach loop where the directories are in some sort of array? If your actions are pretty close to the same, you could consider doing that as well.
