DB file extension typically indicates that information inside the file is stored as structured database data. Various applications can utilize this extension to store data like org chart, sales data, inventory, file list and many more. Such database files could be created by Microsoft Access, SQLite DB Engine, LibreOffice, Paradox, and more. Windows uses Thumbs.DB files to cache thumbnails of the image files stored in the current folder.
If you need to open DB file and the file name is a Thumbs.DB the best way would be to use Thumbs Viewer application. This application is available both for 32- and 64-bit Windows desktop OS and can open Thumbs.DB, browse its content and export thumbnails from it.
To open DB file generated by SQLite database engine you can either use the latest version of SQLite or various tools and utilities created to work with SQLite database. For example, DB Browser for SQLite can open DB file generated by SQLite in a user friendly interface where all tables and their contents will be visible. It also has functionality to add new records to SQLite database, delete or modify records and even execute custom SQL statements on a SQLite DB file.
Frequently DBF file extension is used for databases instead of DB. If your file extension is DBF you may consider checking if file was created by Oracle database engine or Microsoft Access.
If you don't know an application which created DB file in question it might be a good idea to open it in a hex or text editor like Notepad++ or Sublime Text and check if it possible to infer an application from a raw file content.
DB files are generally considered safe because they could not be executed by an operating system. Typically, DB files are not targeted by hackers, so it is safe to open them with corresponding software.
