This must be a contender for the gold-medalist in the least-specific-questions category. Your question sounds like this to me: I've decided to learn to drive, and use a car for it. I'm kinda doing ok so far, but every time I look in my garage, there is no car there. Why is it happening? We could spend all day guessing. Could you tell us please: - Which operating system, - What is the file path (including name) of the SQLite that is opened (and then magically disappearing), - How are you opening it, - Are you using a wrapper, library, compiled-in SQLite, or something else? - Can you open the file with another SQLite tool or the CLI? At least before it disappears? - Have you ever seen the file appear? We are not politicians, we can't inform public opinion on the skantest of suggestions, we need hard evidence and understanding to form ideas or suggestions.
