Windows 10 will prompt you a low disk space warning saying "You are running very low on disk space on Local Disk (C:). Click here to see if you can free space on this drive". 

In this case, how to partition a hard drive Windows 10 to solve low disk space issue? You may consider using the disk partition tool – Disk Management to change partition size. Extend Volume and Shrink Volume are two basic features to repartition a hard drive in Windows 10.

1. When extending a primary partition, there must be unallocated space immediately following the target primary partition.
2. When expanding a logical partition, there must be a free space right adjacent to the logical partition.
3. The target drive should be in NTFS or RAW file system, otherwise, Extend Volume and Shrink Volume features become greyed out.

From the above picture, you know C drive is not allowed to be extended because there is no unallocated space following it. In addition, it is possible that you fail to shrink a volume.
