About DB Files
The .db extension is used by many different programs for their database files, so the contents vary. Most often it is a SQLite database, which phone and desktop apps use to store messages, settings, history and other data. Windows also creates Thumbs.db files to cache thumbnails in folders. Use the File Info tool to see whether a .db file is SQLite before trying to open it.
