File Type 2 Backup File
A BAK file is a backup of another document or file, commonly created automatically by software programs or by the operating system. The file most often just contains a copy of the original file and can be restored to the original by replacing the ".bak" extension with the original extension.
Often BAK files are created by simply appending ".bak" to the original filename. For example, document.doc may have a backup file document.doc.bak.
NOTE: An example program that uses the ".bak" extension is AutoCAD. Windows may also create BAK files for the System.ini and Win.ini files.
