问题

超级用户读者Marina Dunst想知道Windows页面文件的最大大小：

I know that the recommended size for a Windows page file (C:\Pagefile.sys) is around 1.5 to 2 times the amount of RAM. Out of curiosity, what is the maximum size that a Windows Page File can be?

答案

超级用户贡献者Steven、Ramhound和Techie007为我们提供了答案。首先，史蒂文：

The size limit on Windows 7 is 16TB.

When attempting to set a larger amount, Windows will display the error:

This limit is also the maximum file size for a file on Windows 7 NTFS.

Source: NTFS [Wikipedia]

The maximum file size for NTFS on Windows 8 and 10 is larger, but it is unclear if a larger Page File is allowed.

接着是拉姆霍恩：

Based on my research, the maximum Page File size for Windows 8 and 10 is identical to that of Windows 7. The process for changing the Page File’s size has not changed, which means the exact same logic is used.

Techie007的最终答案是：

I believe that 32-bit versi*** of Windows can only handle Page Files up to 4GB in size.
