There are many files on your computer that you may not know the use of
. These files may contain a variety of data and will be specific to the application that was used to initially create them. The BAK files are documents of this type. These are generic files that can be used to store any kind of data. These files can be created as a part of a program during its installation and may play a key role in its running. In that case, deleting these BAK files may result in errors during the functioning of the program. If these files are created as backups of certain documents so that you do not end up losing tem in case your system crashes or there is an error in the running of the program, then these files are automatically replaced once you save the original document. Deleting these files may not cause any major programming errors but will definitely cause a loss in your data that may have been important for you.
Opening a BAK file may be a difficult task as you need to know what application was used to create or modify the file in order to view it properly. If you do not have the access to such information then opening a BAK file may be a bit of a problem. Sometimes BAK files are text only files which means that you can open them using a text editor such as Notepad. However, this may not be true for all BAK files but you can give it a shot. If you still cannot view a BAK file on your computer then you can try converting it to some other format so that it is accessible from your computer through some suitable application. You can open the file and save it in another format or you can download a software from the internet and convert it with that.
