What is the ESP drive in Windows 10?


Before you get to know what the ESP drive does or what it is, let me break down its name for you. The ESP goes by the Extensible Firmware Interface System Partition name. As the name suggests, it is a partition or logical division of a hard disk.


And by extensible, it means that Windows can change or modify the ESP drive for different situations:


  • It is the section of a hard disk drive of a computer. Windows creates such different sections to make it available to the computer operating system as a separate part. It helps the system to run smoothly. Let’s find out what this partition stores so that you can understand  its functionality 


  • It contains the boot loaders files that help Windows to start the boot process, device drivers, or other utilities. These files make sure that all the essential parts of the system work together perfectly. 


  • The ESP drive also stores device or system drivers and they command Windows 10 on how to work with the hardware components of the computer. 


  • The data files and the system utilities are also in this partition. All the information related to the boot process and logs are in the data files. And the system utilities help the windows to run and start without any issue. 


  • If you are running the Microsoft Bitlocker to protect your computer from a data breach, all the data of the Bitlocker will be stored in the ESP drive. And it contacts or works with the Trusted Platform Module to encrypt or decrypt the data from there. 


So, the ESP drive performs a lot of tasks. Especially if you have an internal hard drive only, you must keep the ESP drive. But if you have an external drive, you can remove the ESP drive if you want.
