I want to know how much memory can I upgrade to?

[PC4slightdummy]

I have a Omen Obelisk Desktop 875-00201zCTO/64bit/ Installed Memory 8GB. It says Memory Slot 8GB Kingston 2666MHZ. My Processor:AMD Ryzen 5 2600 six core 3.40GHZ. System board 84FEoo. I have a D drive  with 931GB available. I don't know a lot about PC's so I need help with additional memory. I play The Sims 4 and I downloaded a LOAD of custom content. I am running out of space. Can someone tell me if my system can handle it and what memory do I add? Thank you.

@PC4slightdummy,

First of all, what is the exact model # of this unit.  HP 875-0xxxZ (you have too many numbers).

You have a glaring difference of definitions.

1) Downloads are stored on the hard drive.  The D drive is void of any files, you never saved anything to it.

2) Memory is called memory,  or RAM. It is not stored, it is not saved.

To expand on the excellent advice that @wb2001 already gave you ... you are confusing MEMORY with DISK SPACE -- they are not the same.  The MEMORY is the 8GB you mentioned; the DISK SPACE is what you are running out of on the C drive.

You installed to the C drive, which is done by default, and that is why you are running out of DISK SPACE.

You can not MOVE an existing application from C to D, so instead, you would need to follow the directions that @wb2001 provided and reinstall to the D drive.  That will free up considerable DISK SPACE on the C drive.
