Swap space is a portion of your hard drive that is used as virtual memory. When your computer’s physical memory (RAM) is full, Windows will use swap space to store data that is not immediately needed. This can help to improve performance by reducing the amount of time that your computer spends paging data to and from the hard drive.
There are a few different ways to check swap space on Windows. One way is to open the Task Manager. To do this, press Ctrl+Shift+Esc. Then, click on the “Performance” tab and select “Memory” from the left-hand menu. The “Swap” section will show you the amount of swap space that is available and the amount that is being used.
