To use a file, it must first be opened by the application. This allows the application to access the contents of the file and perform operations on it. Writing to or reading from the file can come after it has been opened, but opening it is the first step. Unlocking a file may be necessary if it is currently in use by another process, but it does not necessarily need to happen before the file is used by the application.
