Bags are typically created by a tool like rosbag

They store the serialized message data in a file as it is received

The data stored within bag files is often very valuable, so bag files are also designed to be easily migrated when msg files are updated. The bag file format stores the msg file of the corresponding message data, and tools like rosbagmigration let you write rules to automatically update bag files when they become out of date.

Bag Tools

• rosbag: unified console tool for recording, playback, and other operations.

• rqt_bag: graphical tool for visualizing bag file data.

• rostopic: the echo and list commands are compatible with bag files.
