Windows 10 Disk Space

You designate a specific amount of space when you partition the hard disk for your system partition. The C drive fills up more quickly than the other disks as you use Windows and install new software. When put together, the system configurations, cached files, and settings total a substantial quantity. Thus, you will eventually encounter a Low Disk Space problem. To address the low disc space issue, the disc size has been raised. Older volumes will be deleted and combined into a C drive to increase the disc’s size.

Important data and files shouldn’t be kept on a C disk for two reasons. The system’s speed and performance are first harmed by massive data stored on the C drive. There will eventually be a disk space constraint as a result. Second, if a virus or Windows upgrade is required, data will be destroyed.

1. Increasing Disk Space in Windows 10 Using Disk management

The native Windows software Disk Management makes it simple to solve the low disk space problem. Disk management has a built-in feature to expand the capacity of the C drive. Disk management basically works by expanding available, unallocated space on various partitions. Only partitions that are adjacent to them, or those that are on the same hard drive as them, can receive additional unallocated space. Also, this approach is useless if the partition you wish to expand isn’t an NTFS one.

So, starting the program is the only way to determine if you can extend the system partition in Windows 10 using this method. Ideally, you’ll locate a sizable amount of free space directly near the C drive. Let’s see the required steps for using the Disk Management method.

Step 1. Start the Extend Volume Wizard

Search for Disk Management in the Start Menu first. Also, you may access it by right-clicking the Windows Start button and choosing it from the menu, or you can look for it under Administrative Tools in the list of programs. Start Disk Management, then use the right-click menu to choose the C disk in the window that appears. To launch the Extend Volume Wizard, select the Extend Volume option. You cannot use this method if the option is grayed out, most likely because no contiguous unallocated space could be detected.

Step 2. Incorporate Unallocated Disk Space

On the first wizard screen, select Next. You can choose the disks you want to work with on the following screen. The list on the left has the available unallocated disk space. If none are accessible, utilizing this method will not allow you to extend your system partition. To add a space to the Selected list on the right, click the Add > button after clicking on the space. To increase the final disk space of the C drive as much as feasible, add as many empty spaces as you can. When finished, click Next to advance to the wizard’s next step.

Step 3. Complete the Changes

Click the Complete button to complete the extension process after carefully reviewing the changes you’re about to make sure there are no errors. After a while, you ought to return to the Disk Management home page with more space on the C disk.

As the amount is supposed to be in megabytes, take care to put the correct number of zeros. Using diskpart is only an option if your system partition is next to an unallocated area, just as the prior technique.

In the event that using Disk Management is not an option, you may always simply move your files from the D drive to another disk or the cloud, erase the D drive, and then use Disk Management to expand the C drive with the extra space.

There are many free and premium partitioning programs available, but for the purposes of this article, we’ll be using DiskGenius Free Edition.

Follow the below steps to learn how to use this method as the last one in this tutorial. While using this method on a laptop, keep in mind to plug it in to not lose power till the end and also disable the sleep mode or hibernation since the process would take up some time.

Step 1. Download and run DiskGenius

The accessible version of DiskGenius must first be downloaded from their official website. Launch DiskGenius Free Edition after downloading and installing it to proceed to the next action.

Step 2.  Go to the Extend Partition screen

A list of all the partitions on your disk drive can be found on the left. Right-click on the system partition (which is located on the C drive by default). Choose Extend Partition from the options.

Step 3. Choose the appropriate partition

Now, you will notice a breakdown of the drive on the Extend Partition screen, with partitions and their volume being clearly displayed. Because DiskGenius will move that space to your C drive, find a partition with a lot of spare space. After determining which partition you want to shrink in order to free up more disk space in Windows 10, click Yes to move on to the next step.

Step 4. Resize the partition

You can specify exactly how much of the new partition you wish to transfer to your C drive in the Resize Partition window. To enter a precise number, either drag the separator bar or use the text box. Also, you have the option to choose to leave some more free space (in case you need to try this again). Click the Start button once you have completed all the necessary configurations. After that, a list of the upcoming modifications will be displayed to you. Click Yes after reviewing them to ensure they are accurate. It will take some time, and your computer might restart once.
