For historical reasons, a pagefile is called a swap file. It is virtual memory. The amount of memory available (to malloc(), FI) is the sum of real memory and swap files, less some overhead for the page tables. The old swap is twice ram rule of thumb was for systems trying to run X with 4 or 8mb real memory. > > The second part of James' reply is precisely what I hoped for: > > (you) can make a new swap partition with eg fdisk and change > > the entry for swap in /etc/fstab.
