How can I divide one partition into two in Windows 10

Windows Disk Management is a built-in utility in Windows that lets you manage your computer's hard drives and storage devices without using third-party software. It provides a graphical interface for performing tasks like creating, deleting, resizing, formatting, and assigning drive letters to partitions.

You can access Disk Management by right-clicking the Start button and selecting Disk Management, or by typing diskmgmt.msc into the Run dialog (Windows + R). It displays all connected disks and their partitions, showing details such as file system (e.g., NTFS, FAT32), capacity, and status.

It’s especially useful for:

1. Shrinking or extending volumes
2. Creating or deleting partitions
3. Changing or assigning drive letters
4. Initializing new disks

Disk Management is ideal for splitting or dividing partitions in Windows 11/10, though it has limitations (e.g., it can’t merge partitions or convert between all file systems) — for advanced needs, third-party disk partition tools are often used.
