IFileProvider Azure File storage

I am thinking about implementing IFileProvider interface with Azure File Storage. What i am trying to find in docs is if there is a way to send the whole path to the file to Azure API like rootDirectory/sub1/sub2/example.file or should that actually be mapped to some recursion function that would take path and traverse directories structure on file storage?

just want to make sure i am not missing something and reinvent the wheel for something that already exists.

[UPDATE]

I'm using Azure Storage Client for .NET. I would not like to mount anything. My intentention is to have several IFileProviders which i could switch based on Environment and other conditions.

So, for example, if my environment is Cloud then i would use IFileProvider implementation that uses Azure File Services through Azure Storage Client. Next, if i have environment MyServer then i would use servers local file system. Third option would be environment someOther with that particular implementation.

Now, for all of them, IFileProvider operates with path like root/sub1/sub2/sub3. For Azure File Storage, is there a way to send the whole path at once to get sub3 info/content or should the path be broken into individual directories and get reference/content for each step?

I hope that clears the question.

    For access the specific subdirectory across multiple sub directories, you could use the GetDirectoryReference method for constructing the CloudFileDirectory as follows:

    var fileshare = storageAccount.CreateCloudFileClient().GetShareReference("myshare");
var rootDir = fileshare.GetRootDirectoryReference();
var dir = rootDir.GetDirectoryReference("2017-10-24/15/52");
var items=dir.ListFilesAndDirectories();

    For access the specific file under the subdirectory, you could use the GetFileReference method to return the CloudFile instance as follows:

    var file=rootDir.GetFileReference("2017-10-24/15/52/2017-10-13-2.png");
