In this article, we'll explain what BAK files are, how to find out what program created the BAK file, and provide some tips on converting them.
What is a BAK file and how do I open it?
A file with the BAK file extension is a Backup file. This file type is used by many different applications, all for the same purpose: to save a copy of one or more files for backup purposes.
Most BAK files are created automatically by a program that needs to store a backup. This could be anything from a web browser that stores backed-up bookmarks to a special backup program that archives one or more files.
BAK files are also sometimes created manually by the user of a program. You might create one if you want to edit the file, but don't want to make any changes to the original. So instead of moving the file out of its original folder, writing new data over it, or deleting it altogether, you can simply add ".BAK" to the end of the file for good measure.
