Searching Azure File Share to match string

It sucks. There's a search directory box in Explorer, so wtf Azure?! Can't search by anything except full directory name even with wildcards. Until now. Search for Directories and Files that match your string.

Note: You'll need Subscription ID, Resource Group Name, and Storage Account name of where you want to search.
