Question
Which of the following is the most important consideration when opening a file on an OS GUI?
- A. File extension Correct
- B. Default permissions
- C. Backup policy
- D. Data compression
Explanation
In a graphical operating system, the file extension tells the OS which file type it is and which associated application should open it when the user double-clicks the file. Permissions decide whether a user may open a file, but they are not what the GUI uses to choose how to open it. Backup policy and data compression have nothing to do with how a file is opened.
