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.

As the files that we will create may contains data, these files will utilize computer resources such as, memory (RAM, Cache) and other resources. While programming, we need these resources as well.

Therefore, It is necessary to open a file when the program needs to work with it and close the file as soon as we have finished using it. The reason is that, it takes computer resources which are limited.
