At times, you need to find out the disk space in total (including used space & free space) on your computer HDD or SSD. The common way to check what is taking up space on my SSD is via Windows Explorer. It's easy but inaccurate to check the total hard drive capacity on a hard drive on which a single partition is created. One partition size equals one hard disk size. However, not for the case that there is unallocated space except for one partition/volume because Windows Explorer won't display the amount taken by unallocated space.
