File extension BAK (.BAK) information

Windows cannot open BAK files?

If Windows is unable to open BAK files you may not have the appropriate program installed or may have a registry related error. BAK files are generated by a range of software as backup files to store information. As such the format of the data contained varies depending on the format of the file of which they are a duplicate. To establish which package created the particular .BAK file it might be necessary to investigate a little. Firstly you can search through the file using a text editor looking for any hints about the original generator. Alternatively the folder in which the file is sits might also give an indication, as well as the time and date the file was created. Scan your system to prevent and identify association errors.
