HD2 Files
HD2 temporary files are created in the following situations:
- When no HDB is linked to the project and the project is started.
- When the SQL server is stopped.
- When the connection from the project to the SQL server is lost.
- When the HDB (STS) is full.
- When the HDB (LTS) is not available.
NOTE: If there are no HD2 files present, it indicates that all temporary data has been saved to the database.
