Have you ever wonder, do all these folders are automatically available in a PC or laptop, or someone creates them. What is the use of all these folders? Can you delete these folders or making any changes in them or their number?

All the above questions will have their answers in the below article. Let’s see what are these folders and who manages them? All these folders, their information, their management is handled by a Microsoft utility called Disk Management.

What is Disk Management?

Disk Management is a Microsoft Windows utility that allows the full management of disk-based hardware. It was first introduced in Windows XP and is an extension of the Microsoft Management Console . It enables the users to view and manage disk drives installed in your PCs or laptops like hard disk drives (Internal and External), optical disk drives, flash drives, and partitions associated with them. Disk Management is used to format drives, partition hard drives, assign different names to drives, change a letter of drive and many other tasks related to disk.

Disk Management is now available in all Windows, i.e. Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10. Although it is available in all Windows operating systems, Disk Management has small differences from one Windows version to another.

Unlike other software available in computers with shortcuts to access directly from Desktop or Taskbar or Start Menu, Disk Management does not have any shortcut to access directly from Start Menu or Desktop. This is because it is not the same type of programme as all the other software available on a computer.

As its shortcut is not available, it does not mean it takes much time to open it. It takes very less time, i.e. a few minutes at most to open it. Also, it is very easy to open Disk Management. Let’s see how.
