No, you do NOT know anything about what is written to pagefile.John Weiss said:I just tried another simple experiment...
Open Explorer. Open the Processes window in Task Manager and activate the VM column.
Access a folder or network drive with Explorer. Watch the VM usage increase. Switch to another
folder or drive. Watch it increase again. Access the folder already accessed. Watch the VM
usage increase yet again!
So, Windows is NOT simply reserving space for future usage; it is writing data to the pagefile
instead of physical RAM, and is apparently NOT reusing that data! Neither is this being done "in
the background" -- it is being done at the time of access, by the foreground process!
Commit charge (PF usage) is allocation, not actual written.
VM usage is simple allocated memory, nothing to do with pagefile.
