• For faster data transfer, Storage Explorer now uses AzCopy v10.8.0. Log files now have more descriptive names and, easier way to clean up old logs. Authorizing via shared access signatures (SAS) is now enabled for ADLS Gen2 accounts. You can now attach to an ADLS Gen2 Storage account, container, or folder via SAS using Storage Explorer.
• Manage Blobs using Azure Storage Explorer Managing blobs is pretty simple using ‘Azure Storage Explorer’ interface as it is just like Windows files and folder explorer. You can create a new container, upload blobs, see them in a listed format, and download them.

The Storage explorer desktop tool is available now in the azure storage accounts section in azure portal. From here we have options to manage,create Blob Containers, File shares and queues. New Blob Containers can be created, deleted and managed –.

One of the more common request we have seen from customers is that they want to use PowerApps and use Azure Blob storage to store their media files. So far, this has not been possible out of the box – and customers have had to use workaround using a custom API (https://powerapps.microsoft.com/en-us/blog/custom-api-for-image-upload/ ). Well, no more. With this update, you can now directly use the Azure Blog Storage connector from PowerApps to load or save images and other media. Not only that, you can share the app with users – and they will be able to use your app without you having to share the account keys to y our Blob store.

Azure Blob Storage Setup

To enable Azure Blob Storage in an app, you will need to get the following information:

• Azure Storage Account Name
• Azure Storage Account Access Key

If your organization has not signed up for Azure Blob Storage, you can follow these steps to sign up:

• Go to https://Portal.Azure.com
• Login with your organization email and password
• Select Create a Resource on the top left

• Search for Storage Account
• Select Storage account – blob, file, table, queue

• Select the Create button
• Fill in the details about your new blob then select Create, this will create the blob storage
  • The name of your blob that you create will be used as the Azure Storage Account Name when you setup your connection
• Once the blob storage is created, you will see a property called Access keys click on that and copy one of the two keys that have been created for you

Canvas app setup for Azure Blob Storage

Let me show you how to quickly build an app where you can display and upload images from/to your Blob store. We will use two Gallery, the first one to browse a container, and the second one that displays the files in the selected container. Finally, we will use some of the controls to show the user the files in your blob storage.

Follow these steps to use the Azure Blob Storage connector in your app:

• Create a new app
• Add the Azure Blob connector to your app by going to View > DataSources > Add a Data Source > New Connection > Azure Blob Storage
• Select the Azure Blob Storage connector and fill in the details that you created.

• Add a new blank vertical gallery by going to Insert > Gallery > Blank vertical
  • Change the layout to a Title gallery by clicking on the gallery then going to the right property panel and clicking on Layout to change it
  • Set the Items property of the gallery to: AzureBlobStorage.ListRootFolderV2().value
  • This will show you the highest-level containers that are available to store / retrieve your files
  • If you do not have any items show, you can download the Microsoft Azure Storage Explorer (https://azure.microsoft.com/en-us/features/storage-explorer/ ) which will allow you to login and add containers

• Add another new blank vertical gallery by going to Insert > Gallery > Blank vertical
  • Set the layout to Image, title, subtitle and body
  • Set the Items property to: AzureBlobStorage.ListFolderV2(Gallery1.Selected.Id).value
  • Change the following items in the data panel
    • Body to Path
    • Subtitle to MediaType
    • Title to DisplayName

• Click on the first image in the gallery and set it to – AzureBlobStorage.GetFileContent(ThisItem.Id) or 'https://YourStorageAccountName.blob.core.windows.net' & ThisItem.Path **
  • You can use the MediaType to pass the path and URL to any type of supported control in PowerApps such as:
    • PDF Viewer
    • Image
    • Audio
    • Video
    • ** Change YourStorageAccountName to your actual store account name if you used that option. This option is only if you set your blob storage to public access. If your blob storage container is locked down (which is the default and recommended) then you can use the GetFileContent method.

Upload Files to Blob Storage

Your app can now display files from blob storage into a gallery, now let’s add a way for users to upload new files to blob storage.

• Add an upload control to send a file to your blob storage by going to Insert > Media > AddPicture
  • Add a Textbox to your canvas app so you can name the file by going to Insert > Text > Text Input
  • Add a button to your app for the user to click on it to upload the file by going to Insert > Button
    • For the OnSelect property of the button add : AzureBlobStorage.CreateFile('myfiles',TextInput1.Text,UploadedImage1.Image)
    • myfiles will need to be updated to the directory you want your files to be uploaded to

Refreshing Galleries Azure Blob Storage

The blob connector does not auto refresh when data is updated in it. To solve this, you can add the following:

• To the button OnSelect property add:
  • ;ClearCollect(TopLevelList, AzureBlobStorage.ListRootFolderV2().value)
• To the screen OnVisible add:
  • ClearCollect(TopLevelList, AzureBlobStorage.ListRootFolderV2().value)
• Update the first gallery you created that contains the high-level folders
  • Set the items to: TopLevelList

You can now try out your blob storage app by playing the app, uploading a file, put a full name (with the extension) in the text box and clicking on the button. Do not forget to change the popup window filter to All Files (button right) when it pops up (if you are trying this out from a browser).

Using your files in an app

Now that you can have users upload files or use the camera / pen and other controls to send the files to Azure Blob Storage, you will want to show those files back to users.

You can check the Media type or file extension to show or hide several types of controls on your canvas.

Try using these based on the example:

PDF Document Property:

If('.pdf' in Gallery2.Selected.Path, AzureBlobStorage.GetFileContent(Gallery2.Selected.Id))

Image Property:

If('image/' in Gallery2.Selected.MediaType,AzureBlobStorage.GetFileContent(Gallery2.Selected.Id))

Video Media Property:

If('video/' in Gallery2.Selected.MediaType,AzureBlobStorage.GetFileContent(Gallery2.Selected.Id))

Audio Media Property:

If('audio/' in Gallery2.Selected.MediaType,AzureBlobStorage.GetFileContent(Gallery2.Selected.Id))

You can also show your user when you do not have a control that will play a certain type of document. Add a label control set the Text to “Document not available in PowerApps” and use this as the visible property:

If('video/' in Gallery2.Selected.MediaType || 'image/' in Gallery2.Selected.MediaType || 'audio/' in Gallery2.Selected.MediaType || '.pdf' in Gallery2.Selected.Path,false,true)

Security for your Azure Blob Storage files

You will want to secure your Azure Blob Storage files. Each container can have a different Public Access Level assigned to it. In Microsoft Azure Storage Explorer, you can click on a blob storage container, go to the actions tab on the bottom left of the screen and view your access settings.

The first setting (no public access) will restrict access from viewing / downloading the file even if the user has the URL to that file. If you want to lock down your files online, this is the setting you need to select. If you select that option and click Apply, you will notice your app may stop showing you any images.

If you are using the GetFileContent like we did above for the PDF then everything will continue to work – AzureBlobStorage.GetFileContent(Gallery2.Selected.Id). If you hard coded in your URL with the storage account name, then you will need do to the following:

To secure your files and allow your app to show them to your users, you will need to setup a Shared Access Signature. This will assign a key to all the files in your container and will not allow them to be shown unless a special key is appended to the URL.

In Microsoft Azure Storage Explorer, you can click on a blob storage container, go to the actions tab on the bottom left of the screen and navigate to Get Shared Access Signature.

Set the expiry time to a date in the future. This will create a key when you click create that will expire based on the date time that you set in the box. Your key will stop working on this date.

Copy the Query string on the next page to use it in your app. In your app append the query string to the end of any URL in a control where you are viewing an item. You can do this in the app directly (not recommended) or store the key in a different data source and use that data source to insert into the key.

For example, in the gallery that is showing images back to your users, you will need to change the image property of that image:

• From: “https://YourStorageAccountName.blob.core.windows.net' & ThisItem.Path
• To: “https://YourStorageAccountName.blob.core.windows.net' & ThisItem.Path & “?st=YourKey”

If you need to lock down your files and have a URL you can send to an outside customer, you can use the CreateShareLinkByPath function. This will lock down the file to a period you can set and generate a URL for that file that can be used by users outside of your app.

To try out the CreateShareLinkByPath function do the following:

• Click on the first record in the gallery showing all your files
• Add a button to the gallery (if you did this correctly, you will see one button per record)
• OnSelect of the button add the following:
  • Launch(AzureBlobStorage.CreateShareLinkByPath(ThisItem.Path).WebUrl)
    • Optional items after the path will show in PowerApps, I use the ExpiryTime to set a timeout for the file an example would look like:
      • Launch(AzureBlobStorage.CreateShareLinkByPath(ThisItem.Path,{ExpiryTime:DateValue('1/1/2050')}).WebUrl)

You can now create or update your apps to include Azure Blob Storage files. You can lock down the files if you would like to and show your users the supported files back in PowerApps.

Sharing an app you made that uses this connector

After your app is made you will want to share that with your team. The wonderful thing with this connector is when you share the app, your team will get access to use the connector automatically and will not have to bring their own key to access the blob storage. With the previous version you would have to give each team member your access information to allow them to use it.

Microsoft Blob Storage Cost

Current users of the Azure Blob Connector

If you are currently using the Azure Blob Connector in your app it will continue to work. As you share your current app with other team members it will continue to work as it did before. If you need to update your app that will also continue to work. However, you will not be able to add new Excel data source from your blob storage.

You can use the following connectors that support Excel as a connection:

• One Drive
• Box
• DropBox
• Google Drive

Additional Resources

As you add Azure Blob Storage to your apps, you can begin to leverage all the power of the Azure Platform.

We are excited to release this functionality to you, let us know what you think.

Acer aspire v5571 driver for mactoylasopa. This article shows you how to use Azure Storage Explorer to manage access control lists (ACLs) in storage accounts that has hierarchical namespace (HNS) enabled.

You can use Storage Explorer to view, and then update the ACLs of directories and files. ACL inheritance is already available for new child items that are created under a parent directory. But you can also apply ACL settings recursively on the existing child items of a parent directory without having to make these changes individually for each child item.

This article shows you how to modify the ACL of file or directory and how to apply ACL settings recursively to child directories.

Azure Blob Storage Explorer

Prerequisites

• An Azure subscription. See Get Azure free trial.

• A storage account that has hierarchical namespace (HNS) enabled. Follow these instructions to create one.

• Azure Storage Explorer installed on your local computer. To install Azure Storage Explorer for Windows, Macintosh, or Linux, see Azure Storage Explorer.

Note

Storage Explorer makes use of both the Blob (blob) & Data Lake Storage Gen2 (dfs) endpoints when working with Azure Data Lake Storage Gen2. If access to Azure Data Lake Storage Gen2 is configured using private endpoints, ensure that two private endpoints are created for the storage account: one with the target sub-resource blob and the other with the target sub-resource dfs.

Sign in to Storage Explorer

When you first start Storage Explorer, the Microsoft Azure Storage Explorer - Connect window appears. While Storage Explorer provides several ways to connect to storage accounts, only one way is currently supported for managing ACLs.

Select Add an Azure Account and click Sign in.. Follow the on-screen prompts to sign into your Azure account.

When it completes connecting, Azure Storage Explorer loads with the Explorer tab shown. This view gives you insight to all of your Azure storage accounts as well as local storage configured through the Azurite storage emulator, Cosmos DB accounts, or Azure Stack environments.

Manage an ACL

Right-click the container, a directory, or a file, and then click Manage Access Control Lists. The following screenshot shows the menu as it appears when you right-click a directory.

The Manage Access dialog box allows you to manage permissions for owner and the owners group. It also allows you to add new users and groups to the access control list for whom you can then manage permissions.

To add a new user or group to the access control list, select the Add button. Then, enter the corresponding Azure Active Directory (Azure AD) entry you wish to add to the list and then select Add. The user or group will now appear in the Users and groups: field, allowing you to begin managing their permissions.

Note

It is a best practice, and recommended, to create a security group in Azure AD and maintain permissions on the group rather than individual users. For details on this recommendation, as well as other best practices, see Access control model in Azure Data Lake Storage Gen2.

What Is Blob Storage Azure

Use the check box controls to set access and default ACLs. To learn more about the difference between these types of ACLs, see Types of ACLs.

Apply ACLs recursively

You can apply ACL entries recursively on the existing child items of a parent directory without having to make these changes individually for each child item.

To apply ACL entries recursively, Right-click the container or a directory, and then click Propagate Access Control Lists. The following screenshot shows the menu as it appears when you right-click a directory.
