text: <s>[INST] OPTIX - Where in the PC is the Project Databases stored. Does anyone know where the DB's are stored in the PC running the runtime ? - I thought it would be project folder related , but it seems thats not the case as i have managed to corrupt a DB once or twice experimenting with SQL queries , and when you open a previously saved / older project, the problem of the DB seems to still exist. Id like to copy it and drop it back into the correct place rather than rebuild from an error. [/INST] Assuming we are talking about an embedded database (DataStore), with the DataStore's In memory configuration value set to false, Optix will create an .sqlite database file with the DataStore's Filename configuration value and place it in the Windows user's AppData directory.  If you don't have a Filename configured, Optix will create a file with some guid-looking filename.  Example path shown below, C:\Users\{username}\AppData\Local\Rockwell Automation\FactoryTalk Optix\Emulator\Projects\{project name}\ApplicationFiles\filename.sqlite. I would also recommend doing an internet search for a DB browser for SQLite.  Makes it easy to see the contents of this embedded database.  Just don't have it, or try to open when running Optix.\n </s>
