Every system comes with a built-in partition. Even so, the system nowadays has sufficient capacity. However, no matter how large the storage capacity is, several factors such as installed apps, cache memory, and temporary files contribute to the overall space usage. These files quickly fill up the available space. You may not notice it or be unaware of it. Yet, it does take up space on your computer. You keep your data in the specified capacity. Some versions of Windows include an extra partition called the window recovery partition.

 In most cases, the partition size is sufficient to hold data. When you have a large amount of data to store, you will undoubtedly need more space. To effectively handle the data in the available storage capacity you need to increase the partition size.
