Intel P-4

I'VE INSTALLED SOME PROGRAMS AND THE C DRIVE IS NOW ALMOST FULL AFTER HAVING SOME MOVIES ALSO IN C-DRIVE, SO I WANNA INCREASE THE MEMORY(really or virtually) FOR SOME EXTRA MOVIES

Hello,
If you would like to increase your driver space then it can be done by using LVM, but I do not think this will work in Windows operating system. So you will need to use linux if you want that feature or tool to use. For windows I do not think this is possible. Also, one more thing memory can be increased virtually, you can not increase a memory really (until you replace it with new hardware). I guess I am correct here.
