    Explanation:
    Disk Management (diskmgmt.msc) creates, formats, extends, shrinks, and deletes partitions. It can convert disks between MBR and GPT (with caveats) and create volumes. For advanced tasks (command line, scripting, or low-level recovery), use diskpart. Always back up data before partition changes.
