swap file

Disk-based RAM extension

A swap file is a file on a computer's storage drive that extends available memory by temporarily holding data that doesn't fit in RAM.

When physical memory fills up, the operating system moves inactive data to the swap file, retrieving it when needed.

This virtual memory technique allows running more programs than RAM alone would permit, though accessing swap is slower than accessing RAM: The system was sluggish because it kept hitting the swap file.
