An SQLITE file contains a database created with SQLite, a lightweight (RDBMS) widely used in application development for storing embedded databases. SQLITE files are often created by software developers for storing data used by their applications.

SQLite databases store data in tables, which may contain multiple fields of various data types such as text or integers. Developers can access and modify this data using SQL queries or "CRUD" (create, read, update, delete) operations. Since databases are self-contained, updates to the database are fully contained within the SQLITE file. However, SQLite may record transaction information in a second temporary file called a rollback journal. An SQLite database may be encrypted using the SQLite Encryption Extension (SEE) or another encryption technology. Developers often encrypt databases within their applications so the data can not be extracted from the program. The SQLite library is freely available and is supported by all major mobile and desktop platforms including Android, iOS, Windows, and macOS. Additionally, all major programming languages provide support for SQLite. NOTE: The file extension ".sqlite" is not always used for SQLite databases. Developers often use a different file extension such as ".dat" or ".db" to conceal the file format.
