Jack complains that his PC takes a long time to open a file once it is clicked to open. He also complains that the overall performance of the computer is slow. On further probing, you discover that his hard drive is using up 90% of the available space. Which built-in system tool should you recommend to him in order to organize the data on his hard drive?
  1. Disk Defragmenter
  2. Disk Cleanup
  3. Format command
  4. PC Doctor
Explanation
Answer: A - Disk Defragmenter is a tool used to defragment the chunks of spread-out data and arrange it sequentially for faster data access.

Key Takeaway: Data is not arranged sequentially on a hard drive. When you try to open a file on the PC, the PC has to look for fragments of data from various parts or sectors of the hard drive. If the hard drive is full of data, the data retrieval process can take longer. As a result, the program takes time to open and the overall performance of the PC is slow.
