\\
__'' General restrictions''__: Azure storage is not a file system, but an object storage. The folder is more like a prefix of the object name. That is why renaming folders is not supported. Folder moves are only possible through copy and deletion.\\
\\
!1. Azure File Share\\
\\
CrushFTP supports Microsoft Azure Shares as a VFS item, it requires a __Storage Account:__ [https://learn.microsoft.com/en-us/azure/storage/common/storage-account-overview]. About Azure file share: [https://learn.microsoft.com/en-us/azure/storage/files/storage-how-to-create-file-share?tabs=azure-portal]\\
\\
The URL should look like (Replace the URL with your corresponding data!):\\
\\
{{{
azure://STORAGE_ACCOUNT_NAME:ACCESSKEY@file.core.windows.net/SHARE_NAME/}}}
\\
You can find those on the Azure portal, under __Storage Account__. From the left-side menu select __Access keys__ to reveal them.\\
\\
[attachments|AzurePortalAccessKey.png]\\
\\
Then paste them on the appropriate fields in CrushFTP.\\
\\
[attachments|AzureConfiguration3.png]\\
\\
When using “Browse…” in the Jobs interface, or plugin interfaces, the UI is slightly different:\\
\\
There is an input field for the file service share: Share Name \\
[attachments|azureRemoteItem3.png]\\
\\
!2. Azure Blob Container\\
\\
CrushFTP supports __Azure Blobs__([https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blobs-introduction]) as VFS item, it requires a __Storage Account:__ [https://learn.microsoft.com/en-us/azure/storage/common/storage-account-overview]. \\
Azure Blob Storage is __not like a normal filesystem__ with folders and deeper levels you can go into.  It's more like S3 where a file’s name contains slashes, which simulate a folder structure but with many limitations when it comes to renaming and truly simulating a normal file system. Folder rename is not supported.\\
\\
The URL should look like this (Replace the URL with your corresponding data!):\\

{{{
azure://STORAGE_ACCOUNT_NAME:ACCESSKEY@blob.core.windows.net/BLOB_CONTAINER_NAME/}}}
\\
[attachments|azure_blob3.png]\\
\\
__Data Lake storage Gen2__: More info on the official website: [https://learn.microsoft.com/en-us/azure/storage/blobs/data-lake-storage-introduction].\\
Turn on the flag if the storage type is the data lake. It connects through __Azure Blob Storage REST API__ [https://learn.microsoft.com/en-us/rest/api/storageservices/blob-service-rest-api].\\
(This is not Azure Data Lake Storage Gen2 REST API: [https://learn.microsoft.com/en-us/rest/api/storageservices/data-lake-storage-gen2])\\
\\
When using “Browse…” in the Jobs interface, or plugin interfaces, the UI is slightly different:\\
\\
To specify the blob container use the input field: Share Name \\
[attachments|azure_blobRemoteItem.png]\\
\\

You need to select the blob type (append blob or block blobs - page blobs are not supported) specified when creating the blob on Azure.

!3. SAS token\\
\\
Azure also can delegate access with a shared access signature (SAS) [https://learn.microsoft.com/en-us/azure/storage/common/storage-sas-overview].\\
In this case, the URL should look like:
{{{
azure://STORAGE_ACCOUNT_NAME:@blob.core.windows.net/BLOB_CONTAINER_NAME/}}}\\
Or
{{{
azure://STORAGE_ACCOUNT_NAME:@file.core.windows.net/SHARE_NAME/}}}\\
\\
[attachments|SAS.png]\\
\\
The __password field should be empty__ and put the SAS token to the "__Shared access signature token__" input field.\\
\\
[attachments|azure_VFS_SAS.png]\\
\\
!4. Authorize access to blobs using Microsoft Entra ID\\
\\
Azure Storage supports using Microsoft Entra ID to authorize requests to blob data. (see more info : [https://learn.microsoft.com/en-us/azure/storage/blobs/authorize-access-azure-active-directory])\\
\\
You will start at the Microsoft Azure portal:\\
[https://azure.microsoft.com/en-us/features/azure-portal/]\\
\\
__Application registration: __Go to the App registrations and click on New registration:\\
\\
[attachments|SMTP Microsoft Graph XOAUTH 2 Integration/new_registration.png]\\
\\
Name it. Select the Microsoft account types. The redirect URL must end with "__register_microsoft_graph_api/__". Then click on register.\\
\\
{{{
http://localhost:9090/register_microsoft_graph_api/
}}}
\\
[attachments|SMTP Microsoft Graph XOAUTH 2 Integration/register_app.png]\\
\\
Under the redirect URL configuration enable the __Access Token__ to be issued by the authorization endpoint:\\
\\
[attachments|SMTP Microsoft Graph XOAUTH 2 Integration/enable_access_token.png]\\
\\
Configure the API permissions:\\
\\
[attachments|azure_api_permission_blob.png]\\
\\
[attachments|azure_user_impersonation.png]\\
\\
On your __Storage Account__ at __Access Control (IAM)__ assign the role "__Storage Account Contributor__" and "__Storage Blob Data Contributor__" to the specified user.\\ 
\\
[attachments|azure_access_control_roles.png]
\\
Access the user's VFS settings and configure the Refresh Token for the remote Azure connection. At __User Delegation Settings__ click on the "__Get Refresh Token__" button.\\
