At present, the split partition function is compatible with NTFS and FAT32 partitions. However, it's important to note that only the unused space within a partition can be split to create a new partition. If a partition is entirely utilized or already unallocated, it cannot be split.

Method 2. Use Disk Management to Split NTFS Partition

If you opt to utilize Disk Management for partitioning, the process involves several steps and can be time-consuming. Additionally, there's a risk of potential data loss.

Here's a brief overview:

  • To begin, access Disk Management by pressing "Windows+R" and entering "diskmgmt.msc" in the Run dialog box.
  • Next, right-click on the large partition you wish to shrink and select "Shrink Volume".
