My sims 4 households keeps on deleting!?

@jiminsiieee  It's possible OneDrive is syncing the contents of your Documents folder with cloud storage.  And since your C drive is so full, maybe OneDrive isn't leaving a copy locally either.  If this is the issue, you can disable OneDrive entirely, or just prevent it from automatically syncing Documents.

Regardless of whether this is an issue, please free up at least 20 GB (total) on your C drive, if you can.  Check your Downloads folder for anything you can trash.  You may also want to move Documents in its entirety to D.  Here's how:

The thing is, on my C drive, it has 25 GB in total in the drive. Most of the stuff on the drive is mainly system files. I don't use OneDrive. So I moved my documents folder, repaired the game, and still nothing.

@jiminsiieee  You can search your computer for an extra Sims 4 folder.  In a File Explorer window, enter "config" without quotes, and look for any file that's in a Sims 4 folder.  Each user data folder will have exactly one config.log in it, and the last modified date on the config file will reflect the last time the game wrote to that folder.

So you'll be able to tell which folder the game is currently reading.  Then you can move your saves and Tray items (you did say you could still see them, right?) to the corresponding subfolders in the Sims 4 folder that's currently being used.

I found the config file, except that It is a text document. How do I know which are the corresponding subfolders that are still are being used?

@jiminsiieee  Look at the last modified date on the config file(s).  The one that has the same time and date as the last time you launched the game is the one that the game is using.  The Sims 4 folder it's in is the correct folder, and all of the subfolders inside it are being read as well.

So, which folder should I move the trays and the saves to? (sorry for asking too much)

@jiminsiieee  Make sure you've found the correct Sims 4 folder, as in, the one with the config.log that has a last modified date from the last time you opened the game.  Inside that Sims 4 folder, remove the Saves folder that's already there, and put the Saves folder that has your old saves inside instead.  Do the same with the Tray folder.

When you remove the old Saves and Tray folders, don't delete them yet, just in case you realize there's something inside you want.  Just move them somewhere else for now.

I did what you told me to do and still nothing. I think I missed something because I'm unsure if I did it right.

@jiminsiieee  Okay, maybe it's easier if you tell me where everything is.  Please go back and find that config file that's in the Sims 4 folder the game is using.  As in, it has a timestamp from the last time you launched the game.  When you're looking at that file in a File Explorer window, look above the list of files and folders, and you'll see a file path (e.g. Documents\Electronic Arts\The Sims 4).  Please copy that file path and paste it here.

For the saves folder that contains your saves, please do the same, and also for the Tray folder that contains your content.  If you list everything here, it'll be easier for me to describe exactly what to do.
