Answer:
A. Make sure you have the correct software to open it.
Explanation:
If a computer file will not open, what you should do is to make sure you have the correct software to open it.
Sometimes, computer users make the mistake of opening files with the wrong software application or program, this often leads to an error due to the incompatibility of the software application with the particular file.
Basically, all software applications are designed and developed for use with specific file extensions or formats and as such, when used to open a file it isn't developed for, it result in an error.
For instance, you cannot use Microsoft Word to open a Coreldraw file or to play music and video files.
Hence, it is necessary and important to ensure that you have the right software associated with a file format before opening any file.
Additionally, actions such as changing the name of the file, continually clicking or opening the file and pressing F1 would never open the file because of the incompatibility issue.
