The .BAK file format refers to Backup Plus files. These kinds of Bakup files can be generated by any application software, mostly on windows based devices. These files primarily store the backup data of the application software or other data files.
The most common scenario when a .BAK file is created is when an application software is writing to disk that would cause the overwriting of some existing data, in which case, it would automatically create a backup file. Bak files can generally eat up a lot of disk space, hence it is recommended to clean them up at regular intervals.
