Yes, depending on the amount of ram and system settings, mine are combined: 8.66 GB (9,305,751,552 bytes)
I have 32GiB Pagefile and 16GiB Hiberfile. It all depends on RAM. Usually, the Pagefile is 1.0 to 1.5 times the RAM, and the Hiberfile is 40% to 100% of RAM. Windows 10 should also have a third file, swapfile.sys.
I found this (see picture) using WinDirSat, what that means!!! Can't find and access this HDD space. Hi!
