Question

When naming a file and using the iMac, what should you never do?

1) Use more than five letters
2) Start the name with a capital letter
3) Start the name with a period
4) Use a number in the name

Answer 1

In the macOS operating system used by iMacs, starting a file name with a period hides the file from view in the Finder. There are no restrictions on using more than five letters, capital letters, or numbers in file names.

Step-by-step explanation:

When naming a file on an iMac, you should never start the name with a period. This is because files with names starting with a period are considered hidden files in macOS and other UNIX-based operating systems. While there are no issues with using more than five letters, starting with a capital letter, or using a number in the name, starting with a period would make the file invisible in the Finder without using special commands or settings.
