 - Data source without credential enables external tables to access publicly available files on Azure storage.
 - Data source can have a credential that enables external tables to access only the files on Azure storage using SAS token or workspace Managed Identity - For examples, see [the Develop storage files storage access control](develop-storage-files-storage-access-control.md#examples) article.
 
-### Remarks
-When using external tables in a **dedicated** SQL pool to read data from external files, keep the following in mind:
-- Files and folders must remain unchanged during the execution of the statement against the external table.
-- If the referenced files or folders are modified while the statement is running, the operation may fail to complete successfully, or produce inconsistent or unreliable results.
-- Before running queries that read external data, ensure the source files and folders are stable and are not updated, deleted, or replaced during execution.
+## Remarks
+To ensure reliable query execution, the source files and folders referenced by external tables must remain unchanged throughout the duration of the operation.
+- Modifying, deleting, or replacing any referenced files or folders while the query is running may cause failures or lead to inconsistent results.
+- Before querying external tables in a dedicated SQL pool, verify that all source data is stable and will not be altered during execution.
