 ## Authentication
 
-This article uses a simpler authentication approach with Data Lake Storage Gen1 where you are prompted to enter your Azure account credentials. The access level to Data Lake Storage Gen1 account and file system is then governed by the access level of the logged in user. However, there are other approaches as well to authenticate with Data Lake Storage Gen1, which are **end-user authentication** or **service-to-service authentication**. For instructions and more information on how to authenticate, see [End-user authentication](data-lake-store-end-user-authenticate-using-active-directory.md) or [Service-to-service authentication](data-lake-store-authenticate-using-active-directory.md).

 You can upload your data to Data Lake Storage Gen1 directly at the root level, or to a directory that you created within the account. The snippets in this section demonstrate how to upload some sample data to the directory (**mynewdirectory**) you created in the previous section.
 
 If you are looking for some sample data to upload, you can get the **Ambulance Data** folder from the [Azure Data Lake Git Repository](https://github.com/MicrosoftBigData/usql/tree/master/Examples/Samples/Data/AmbulanceData). Download the file and store it in a local directory on your computer, such as  C:\sampledata\.
 
 ```PowerShell
-Import-AzDataLakeStoreItem -AccountName $dataLakeStorageGen1Name -Path "C:\sampledata\vehicle1_09142014.csv" -Destination $myrootdir\mynewdirectory\vehicle1_09142014.csv

 ```

 To rename a file, use the following command:
 
 ```PowerShell
-Move-AzDataLakeStoreItem -AccountName $dataLakeStorageGen1Name -Path $myrootdir\mynewdirectory\vehicle1_09142014.csv -Destination $myrootdir\mynewdirectory\vehicle1_09142014_Copy.csv

 ```
 
 To download a file, use the following command:
 
 ```PowerShell
-Export-AzDataLakeStoreItem -AccountName $dataLakeStorageGen1Name -Path $myrootdir\mynewdirectory\vehicle1_09142014_Copy.csv -Destination "C:\sampledata\vehicle1_09142014_Copy.csv"

 ```
 
 To delete a file, use the following command:
 
 ```PowerShell
-Remove-AzDataLakeStoreItem -AccountName $dataLakeStorageGen1Name -Paths $myrootdir\mynewdirectory\vehicle1_09142014_Copy.csv

 ```
 
 When prompted, enter **Y** to delete the item. If you have more than one file to delete, you can provide all the paths separated by comma.
 
 ```PowerShell
