What uses so much of my SSD Memory?

[TPVS]

I'm looking for help with my memory. My SSD has 218GB of storage space. When I checked last time, I have used a bit less  then 100GB of storage with installed programmes and all my documents, video's etc. I get that the system en hardware used a substantial amount of memory, but I have like 3 GB left on my laptop. Does the system really use more then half of my SSD storage?

Hello;

Allow me to welcome you to the HP forums!

You're mixing different terms and that makes the situation confusing.

The SSD is "disk space", not system "memory", and it's not unusual for Win10 64-bit to use 40GB or more of disk space -- but even then, with a bunch of apps installed, I would guess you would not be using over 70GB of disk space.

You say you have only 3GB remaining?  IS that disk space or system memory? And, HOW are you determining that?

Sorry for the confusion. I'm talking about the local disk "Windows (C:)", right now it says that there's 2,55GB of 218GB is available. If I add up the space used by documents, videos etc. I barely reach 10GB. When you open your control panel and go to the tab where you can remove or modify programs/applications,  for me it says on the bottom that the total size is 79,3GB (140 apps installed). So when you combine those two numbers,  you don't even reach 100GB. So, because I'm running out of storage, my question is where the other 100GB went. I know that system software etc. uses a lot of the storage, but still it seems much in my opinion. Thank you!

OK, now wer'e straight on that ...

There may be folders on your C: drive named $Windows.~BT and $Windows.~WS. These are used by the Upgrade tool to store files needed for the Upgrade. If these are hidden, will have to change your settings in File Explorer to see them, but once you find them, then remove the folders.

Also, you may need to remove the Windows.old folder.  Here are the instructions:  http://www.howtogeek.com/223821/what-is-the-windows.old-folder-and-how-do-you-delete-it/
 
Additionally, here are some Win10 forum threads about recovering disk space:

Once these are gone, you have a lot more free space in the C: drive.
 
Good Luck
