If you build Duplicati in Debug mode (default) it will use “portable” mode and place all files in the `bin/Debug` folder.

Not sure what you mean. The SQLite file is how it is, you can just use the `sqlite3.exe` tool on the database.

Unfortunately, it uses the [RC4 “database scrambling”](https://www.sqlite.org/see/doc/trunk/www/readme.wiki) on Windows, so you may need a copy of `sqlite3.exe` with the RC4 support compiled in.
