Most of us know about this, but what a great reminder!. . . Privacy-conscious users are familiar with deleting files securely, that is, destructively with overwriting and with wiping free space on their disks. But two items that often get overlooked are the swap file (or swap partition), and the hibernation file. Let's start with the swap file. This is an area of your hard disk where data previously held in RAM is written, and later read, to "free up" physical memory and make it available for other tasks. Data swapped from RAM to disk is sometimes called "virtual memory". Your computer can read from RAM much faster than it can read from the disk, but RAM is expensive, whereas disk space is comparatively cheap and usually plentiful. Thus, it's not unusual for a system to have a swap file of 1GB or more. FULL STORY

I wondered about this line: "First, and most obviously, don't use a swap file or swap device. If you've got plenty of RAM, you might not need anything more." But if you've got plenty of RAM it won't use the swap file anyhow, so it seems odd to disable it and risk running out of luck if it should ever be required. DerekW
