If you discover that your computer is stalling or acting sluggish because it is saving too often,
you can always increase the interval to something higher.
Tell Windows to Show File Suffixes
Operating systems sometimes hide file suffixes from the user to simplify the interface. This can
lead to confusion, however, as the suffixes provide you with an important clue as to what the file
is you are looking at, work on, or submit for credit.
I would strongly recommend setting your operating system to show file suffixes by going to the
View tab and checking the box to see the File name extensions (In Mac, go to Finder -
Preferences - Advanced - Show all filename extensions).
