Azure Data Lake Gen2 Storage Account blob vs adf choice

I am new to Azure Data Lake Storage Gen2 service. I have a Storage Account with "Hierarchical namespace" option Enabled. I am using AzCopy to move some files and folders. From the command line I can - within the address string - use either the option "blob" or the "adf" string tokens:

'https://myaccount.blob.core.windows.net/mycontainer/myfolder'

or

'https://myaccount.adf.core.windows.net/mycontainer/myfolder'

again within the .\azcopy.exe copy command.

"Apparently" both ways succeed giving the same result. My question is: is there any difference if I use blob or adf in the address string? If yes, what is it?

Also, whatever string token I choose, in the Azure portal a file address is always given with the blob string token..

thanks

In the storage account Endpoint page, you can see all the available endpoints for you to use for their services.

Both blob and dfs work for you because both of them are supported in Azure Data Lake Storage Gen2 . However, in Gen1, you may only have the blob service but not the dfs service available (like below). In that case, you won't be able to use the dfs endpoint.
