Extending storage size in Windows 11 lets you increase the capacity of a Storage Space within a Storage Pool.

Storage Spaces is a Windows tool that lets you group several physical hard drives together. This creates one larger, virtual drive or “storage pool” that acts like a single drive in File Explorer, complete with a drive letter.

You can make a Storage Space appear much larger than your current pool’s capacity. This means you can plan for future storage needs and add more physical drives to your pool later when you need them.

You might need to extend your storage size when you’re running out of room for important files and programs on your PC.

⚡ Quick Answer

Open Settings, navigate to System > Storage > Advanced storage settings > Storage Spaces. Select your storage pool, click Properties, then click Extend. Enter your desired new size and click OK.
