In MySQL, an authorized user may lack file permissions due to specific security restrictions or privilege settings. MySQL's `FILE` privilege is required for operations like `LOAD DATA INFILE` or `SELECT ... INTO OUTFILE`, which interact with the server's file system. If this privilege is not granted, the user will encounter permission errors.  

**Example:**  
If a user tries to run:  
```sql
SELECT * INTO OUTFILE '/tmp/data.csv' FROM my_table;  
```  
But lacks the `FILE` privilege, MySQL will return an error like:  
```
ERROR 1045 (28000): Access denied for user 'user'@'host' (using password: YES)  
```  

To resolve this, grant the `FILE` privilege explicitly:  
```sql
GRANT FILE ON *.* TO 'user'@'host';  
FLUSH PRIVILEGES;  
```  

For secure file operations in cloud environments, **Tencent Cloud's TencentDB for MySQL** provides managed database services with granular permission controls. It ensures compliance with security best practices while allowing authorized file operations through proper privilege management. Additionally, Tencent Cloud's **COS (Cloud Object Storage)** can be integrated for secure file storage, avoiding direct file system access on the database server.
