Opening BAK files
Did your computer fail to open a BAK file? We explain what BAK files are and recommend software that we know can open or convert your BAK files.
What is a BAK file?
The .bak file extension is used for general backup files. A large number of applications and computer processes use the .bak extension to create backups of documents that the program is creating.
The .bak file extension is a common file extension for the files that are created by the auto-save features that are found in many computer applications. For example, when you are editing a document in Microsoft Word and the auto-save feature kicks in, a .bak file will be created.
Files with the .bak extension are also commonly created before your computer begins to execute a complex operation, ensuring your data will be restored if something happens during the process.
These files are normally automatically deleted by the application that created them when the file is no longer needed.
Software that will open, convert or fix BAK files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
