Hi ,

Thanks for reaching out to Microsoft Q&A.

• Ensure you have the appropriate access level (such as "Storage Blob Data Contributor") to view blobs in the container or directory.
• If you're using Azure AD authentication, verify that your account has been granted the necessary role assignments at the correct scope (container or directory level).
• If using SAS tokens, ensure the token has read (r) and list (l) permissions.
• Verify that the file was uploaded to the intended directory. Sometimes, files might be uploaded to the root container instead of the subdirectory.
• Use tools like Azure Storage Explorer or Azure Portal's "Search by Prefix" feature to locate the file.
• The Azure portal interface might occasionally cache data. Clear your browser cache or try accessing the portal in incognito mode.
• Use Azure Storage Explorer to access the storage account. It often provides a more reliable view of the storage hierarchy than the Azure portal, confirm whether the file is visible. If visible, it's likely a portal display issue.
• Check if the uploaded file's name includes special characters or if it matches any filters (like search filters) applied in the portal interface.
• If soft delete or versioning is enabled, verify that the file isn't in the deleted state. You can check this through the "Manage deleted blobs" option.
• Enable storage diagnostics or use the storage account's monitoring logs to confirm whether the upload was successful. Check the Activity Log for any related errors.

If none of these steps resolve the issue, consider re-uploading the file while monitoring the Storage Explorer or Azure Portal closely for any errors. If you still encounter problems, reaching out to Azure Support with the Activity Log details would be the next best step.

Answer 2

Sometimes, a refresh in the Azure Portal or Storage Explorer may not immediately show the changes, even though the file is uploaded successfully. If you're using Azure Storage Explorer or Azure Portal, ensure you are navigating correctly into the Directory. The folder view in the Azure Portal sometimes takes a little while to update, especially for large or newly uploaded files.

You can use the Azure Storage Explorer or Azure CLI to list the contents of the directory:

Using Azure CLI:

 az storage fs file list --account-name <your-storage-account-name> --file-system <your-container-name> --path <your-directory-path>

This command lists the contents of a directory within the ADLS Gen 2 container, which can confirm if the file was uploaded and is located in the correct directory.

If the file appears in Azure Storage Explorer or CLI but not in the Azure Portal, the issue could be related to the portal’s refresh behavior.

The tool you're using to upload the file might not be correctly placing it in the desired directory. Ensure you're selecting the correct directory when uploading the file. If you're uploading using the Azure Portal:

• After selecting the container, navigate into the directory you created and ensure you're uploading the file into that directory.
• Alternatively, you can try uploading using Azure Storage Explorer or Azure CLI.
