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.
