<1> Paging File:
     |
     |__ o. A page file (also known as a "paging file") is an optional, hidden system file on a hard disk. 
            The page file can be used to "back" (or support) system crash dumps and extend how much system-committed memory (also known as “virtual memory”) a system can back. 
            It also enables the system to remove infrequently accessed modified pages from physical memory to let the system use physical memory more efficiently for 
            more frequently accessed pages.
	 
	 
	 
	 
	 
<2> Sometimes the C: drive growing fast, and hard to figure out which file is eating the disk space:
     |
     |__ o. One method is checking "Resource Monitor" on Task Mananger => Disk => Sort which file is being listed at the top of "write".
     |
     |__ o. Majority of the page file name would be "c:\pagefile.sys (Page File)".
	 
	 
	 
	 
	 
	 
<3> Since page file is a hidden file on Windows system, so it would not be listed in file explorior or even displayed by command line.
     |
     |__ o. One method is installing Cygwin tool, and give "ls -ltra" to show the detail of the file.	 
	 
	 
	 
	 
	 

<4> Follow the hint to address the page file size:
     |
     |__ O. Computer => Property => Advanced => Performance Tab => Settings => Advanced => Virtual Memory
