How to augment swap space

[SignorCastello]

Hi everyone, sorry if I ask this simple question.
I have a lot of apps running, and I've got this situation:

Right now, my system is running very very very slowly, and new apps I open continue crashing.
How can I augment my swap space to, say, 12gb? I have an HDD so that's not a problem.

You can check out this guide:

Swap & Swappiness Explained

------------------ What is SWAP? ------------------- A: SWAP is a backup to DRAM. SWAP is the action of moving DRAM file's to your Hard drive. ---- How SWAP works ---- SWAP is a dedicated partition/file (space), created to assist the physical memory (DRAM). When the DRAM is full, or reaches the set parameters, the system will move idle App's (Process), to the SWAP space. This action frees up the DRAM. Thus running the Priority Process needed. (Making the machine preform better). ---…

Although swap is not really meant to replace actual physical memory. You should consider reducing the number of programs running and/or increase the memory on the system.

Hi, this guide did not help me, because there are no instructions on how to expand the swapfile.
But I made a quick search on the forum and found an @Aravisian post that fixed it.
