Disk partitioning is an essential task for organizing and managing the storage on your Windows system. Partitions allow you to separate your operating system, applications, and personal data, making it easier to manage and secure your files. In this article, we will explore how to create and manage disk partitions in Windows using both the graphical interface and command-line tools.

Creating and Managing Partitions Using Disk Management

Disk Management is a built-in tool in Windows that provides a graphical interface for managing disk partitions. Here's how to use it:

1. Open Disk Management:

   • Press Win + X and select "Disk Management" from the menu.
   • Alternatively, you can open the Run dialog (Win + R), type diskmgmt.msc, and press Enter.

2. Shrink an Existing Partition:

   • Right-click on the partition you want to shrink and select "Shrink Volume."
   • Enter the amount of space to shrink in MB and click "Shrink."

3. Create a New Partition:

   • Follow the wizard to specify the size, assign a drive letter, and format the partition.

4. Format a Partition:

   • Right-click on the partition you want to format and select "Format."
   • Choose the file system (NTFS, FAT32, etc.), allocation unit size, and volume label. Click "OK" to format.

Creating and Managing Partitions Using Command Prompt (CMD)

For those who prefer command-line tools, DiskPart is a powerful utility for managing disk partitions in Windows. Here's how to use it:
