CategoryBackup Files
File Format Description

Backup file created by adb (Android Debug Bridge), a command-line tool included with the Android SDK; can include both apps, system, and user data from an Android 4.0 or later device; used for saving and restoring device snapshots.

Often AB backups do not include the .APK apps themselves, but only the device's app and system supporting data. For example, you can backup the data of a connected Android device without the APK files by typing the following command:

adb backup -all

This creates the file backup.ab in the current directory. To include the APK files as well, use the following command:

adb backup -apk -all

To restore an AB backup file to the device, type the following command:

adb restore backup.ab

The adb program also includes options to include or exclude other types of data and to specify the backup filename. Consult the ADB documentation for further information.

CategoryAudio Files
File Format Description

Audio file used by Ambling BookPlayer, an audio player for Android-based mobile phones; adds the ".ab" extension to a normal .MP3 file (or other audio file) and makes the compound extension ".ab.mp3;" used so that downloaded Ambling BookPlayer files aren't mixed with other audio files played by other music players.

Ambling BookPlayer has a preference named "Add .ab Extension" that controls whether or not the ".ab" extension is added to audio files. You can uncheck this option to disable file extension renaming.
