I am trying to test some of the changes locally on Azure storage emulator and try to attach the storage emulator to The storage explorer.

But in the storage Explorer shows only the list of table, blobs and queues endpoint, not file endpoint.

So I can add file endpoint. Or it is not possible?
Currently, Azure Storage Emulator does not Support File Share.

Here is a similar issue, you could refer to it.
