Best Way How to Check TOTAL Size of Hard Disk Space in Windows

In File Explorer, you just need to right-click the only local disk (C:) and select Properties. Finally, the size of C drive will be shown in front of you. That is the total capacity of your hard disk. However, if your hard disk has several partitions, it will be a massive hassle that you need to check the size of each partition space and add them up to get the total size of hard disk space. Fortunately, you don’t have to do that. In this post, we will walk you through how to check the total size of hard disk space in Windows 10/8/7 without any third-party tool.

If you just want a rough figure in GB, delete the last 9 digits of the string. So I have a 250 GB and a 1000 GB disk, which is correct. If you need an exact number, divide that number by 1073741824 (which is 1024*1024*1024). Therefore, I get a 232.88 GB drive. Why not 250 GB? Keep reading and I will tell you why below.

Notes: You might be confused about the total space of your hard disk that you found shows less space than advertised. For example, the advertised space of my SSD is 250GB but the result I found is 233.83GB. The reason for this difference lies in the different computing ways between the hard drive manufacturers calculate and advertise and the computers actually use. The hard disk manufacturers use decimal bytes, so, 1GB = 1,000MB = 1,000,000KB = 1,000,000,000 bytes. It has been an industry standard in advertising storage space. If the hard disk manufacturer advertises the capacity of a hard drive is 250GB, it contains 250 * 1000 * 1000 * 1000 = 250,000,000,000 bytes. However, computers use the binary bytes, so the computers convert the number of bytes into gigabytes by dividing by 1024 rather than 1,000.So, 250,000,000,000 bytes = 250,000,000,000 / (1,024 * 1,024 * 1,024) = 233.83GB. That’s why the total hard disk space shows less than actual.
