CategoryDatabase Files
File Format Description

Database file used on mobile devices such as Android, iOS, and Windows Phone 7 mobile phones; often stores contacts and SMS information but may store any type of device or application data; commonly stored in an SQLite database format but may also be locked or encrypted so the user cannot see the data directly.

DB files on mobile phones generally are not meant to be opened or edited manually, since they are support files that include information for the device or for an application.

One example of a DB file is sms.db, an iOS support file that stores the user's text messages (located in the /private/var/mobile/Library/SMS/ directory on the device). Another example of a DB file is consolidated.db, a database file on iOS devices that automatically tracks location information.
