Can I/Should I/How do I get rid of this?

[robnyt]

Using DVD Decrypter and DVD Shrink to backup DVD's. Did a few already and deleted the copies off my hard drive. However, in my D: drive I have the following:

DVD_VIDEO.ISO 4,571,792 KB ISO File
pagefile.sys 1,024,000 KB System File

When I double-click the ISO, it opens DVD Decrypter. Double-click System file tells me I could damage my computer by doing anything. What should I do. Seems like A LOT of KB on my computer.

Windows OS's use a technique called "Virtual Memory" -- this allows more active applications and services than would be available if the OS were restricted to just the physical memory (RAM) you have installed.

It does this by "paging" chunks of memory in and out, as needed, to your hard drives.

By default, Windows OS's manage this memory automatically, without input from you. And in this case, Windows elected to place a paging file on your D: partition/drive.

For more information, search for "virtual memory" in Windows Help.
