What are AB files and how to open them

Are you having problems opening an AB file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is an AB file?

An .AB file is an Android Adb Backup file.

Android Adb Backup (.ab) files are a type of data archive used to back-up data from user devices. They are generated using the Android Debug Bridge (adb) command-line tool, which is part of the Android Software Development Kit (SDK).

The adb tool creates this file when backing up device data and stores app-, system-, and other types of information inside it. It can be used with various programs that support the format, allowing users to access its contents.

To open a .ab file, an adb utility program is needed; third-party options may also be available. This will enable users to extract the stored content, such as applications or settings, and restore them to either the same or a different device.
