I have an Acer Aspire 5 laptop and have upgraded 16GB from 8GB. However, I see 20 gb in the Task Manager. The BIOS also says 20GB. Not that I want to complain, but I would like to know why I'm supposed to have 20GB with a 16 GB ram chip.
Is read incorrectly and displayed incorrectly. But is not a problem…
This is a swap file that Windows creates itself.
The size is calculated automatically and is saved as storage space on C: /.
As long as you don't need the storage space, I would just leave it as it is.
