Answer:

Open a file when the program needs to work with it and close the file as soon as you have finished using it.

Explanation:

In programming, we have some files that are stored in memory, or created in some other section of the program to save information.

for example, we want to save the data of a class or school faculty to create a database. For this purpose I need to create a file.
