How do I see the (default) page size for Microsoft Windows 10?

How do I see the (default) page size for Microsoft Windows 10?

I want to see the default page size of my system (x64), because I want to know how many bytes are fetched on each read operation.

Where do I find this quantity. I've read some places that FileAlignment is set to 512 by default, but I'm not sure whether these things are the same.

调用GetSystemInfo ,查看dwAllocationGranularity
