How to Check Free Space on Hard Drive - PC Hardware Questions & Answers

Janice writes in with a hardware question

Question:I want to know how much space is left on my hard drive. When I check, it says 2 things: DATA (D:) 100% free; ACER (C:) 30% free. What exactly does it mean, do I have 2 hard drives and when the other is full will it jump to the other? What does it mean?

Answer: What you are seeing is how much free space is left on each drive. It looks as though your computer came with a second hard drive (data) or someone added one to it. When you install programs they will be placed on your C drive unless you tell the software differently during installation. Any documents and photos that you put in to your Documents folder will also be placed on your C drive sincethat's the default location. If your C drive gets full it won't start using your D drive to store files. You can use the D drive to store photos or music if you want to keep your C drive from filling up. When your C drive gets too full it starts to affect performance and will slow your computer down.
