You know, I didn't know there was a difference between swap part(s) and swap files. Whenever I do an installation, I create (single os-linux only): /dev/hda1 ==>> /, /dev/hda2 ==>> extended, /dev/hda5 ==>> /tmp, /dev/hda6 ==>> /usr /dev/hda7 ==>> /swap (the size allocated to this one, to me, has depended on the amount of physical mem. I usually double it - I also determine whether to make one or more partition -) /dev/hda8 ==>> /home /dev/hda9 ==>> /usr/local (this one depends on the purpose of the system) /dev/hda10 ==>> /var I create /swap "partition(s)". I'd like to know what is a swap file and its purpose. Does the system create swap file as it needs them based on swap partitions? Are they temporary files? What's their relationship in regards to the performance of a system? Thanks Aaron.
