What Is Extended Partition in Windows 10?
Contents

In Windows, you can add more space to existing primary partitions and logical drives by extending them into adjacent unallocated space on the same disk. To extend a basic volume, it must be raw or formatted with the NTFS file system.

What is the difference between a primary and an extended partition?

Primary partition is a bootable partition and it contains the operating system/s of the computer, while extended partition is a partition that is not bootable. Extended partition typically contains multiple logical partitions and it is used to store data.

What does it mean to extend a partition?

An extended partition is a partition that can be divided into additional logical drives. Unlike a primary partition, you don’t need to assign it a drive letter and install a file system. Instead, you can use the operating system to create an additional number of logical drives within the extended partition.
