Do you want to add unallocated space to C drive when it reports low disk space warning on Windows 8? Unallocated space is a volume that has not been formatted and your computer usually cannot write any data to this volume. Therefore, you can add unallocated space to any other partition on the same hard drive on Windows 8 if you receive low disk space alert message on C drive.
Usually, you can add unallocated space to C drive on Windows 8 to resolve problem when you run into following situations:
1. When you boot your computer, Windows 8 always says that C drive is running on low disk space and asks you to delete unnecessary files to free up disk space. In this situation, deleting files cannot resolve problem thoroughly, so you can add unallocated space to extend C drive on Windows 8.
2. PC fails to upgrade Windows 8 to Windows 10 since there is not enough free space on system partition. Since the release of Windows 10, Microsoft allows Windows 8 users to upgrade their operating system to Windows 10 for free. Many Windows 8 users would like to do so, but they fail to complete the upgrading since system partition runs out of disk space on Windows 8. In this situation, you can also add unallocated space to system partition to ensure that it has enough available space for OS update.
3. If the C drive shows red bar on Windows 8 and your computer runs more and more slowly, you also need to add unallocated space to c drive to resolve the problem. In addition, Windows 8 might often stop responding or freeze up when C drive has insufficient space.
You can perform many tasks on Windows 8 Disk Management, while shrinking volume is a common feature under Disk Management in Windows 8. You just need to select a partition that still has lots of available space and shrink it, after which you can get some unallocated space.
Tip: You can shrink more than one partition to create unallocated space.
Suppose there is an empty partition on Windows 8 and you have never stored any data to this partition, do you want to add the space of this partition to C drive when it is running out of disk space? In this situation, you just need to delete this empty partition in Windows 8 Disk Management, after which the deleted partition will show as unallocated volume. When you delete a partition, all data will be erased at the same time. Therefore, you had better not perform this operation if there is no empty partition on Windows 8.
With existing unallocated space, you can free to add the unallocated space to system partition on Windows 8 with either of following methods:
1. If the unallocated space is contiguous to system partition, you can right click system partition under Disk Management in Windows 8 and click "Extend Volume" option to add the unallocated space to system partition.
2. If the existing unallocated space is not contiguous to system partition, you need to rely on partition software to move the unallocated space close to the system partition and then add the space to the system partition.
