Your computer is taking longer than usual to open files and you notice that your hard drive light stays on longer than usual. which of the following is a possible solution to counteract this?

You might need to defragment your hard disk.

The process of locating the noncontagious fragments of data, rearranging the fragments and restoring them into fewer fragments is what is called disk defragmentation. It is like taking pieces of a jigsaw puzzle and storing them in different boxes along with other pieces from other puzzles.
If your computer system takes longer periods to open and close files, it is because the fragments are spread all over. You can fix this problem by putting all the pieces of the puzzle back together in the right boxes. This is done by defragmenting your drive.

What's the rest of it? lol
