Just discovering the 'Tray' Folder :(
So, my game has been a bit slow to load recently so I thought I'd sort out my screenshots folder. I looked at a few more folders and opened the Tray folder - and oh dear!! Mine contains 3955 items, wh...

The easiest thing to do, without getting technical, is to just delete households and lots from your library in game. It will delete the files from the tray folder in the process.
Or you could make a backup of the entire tray folder somewhere on your hard drive or on an external drive and then start deleting the things you think you won't use anymore. That way you can still get back everything by putting the files from the backup in the tray folder.
I have a habit of going through my tray folder from time to time and backing up every creation seperately, but that is a somewhat technical process. It isn't really hard once you get the hang of it, but it is a bit of a dull task, you just have to keep an eye on the time stamp of the files and retrieve the right trayitem file (if you've shared a creation to the Gallery, or updated its description, it may get a different time stamp).
I think this is the easiest tutorial: http://lorisims.net/tutorials/english/sims-4-export-of-lots-and-sims/ (personally I skip the uploading and downloading from the gallery part, but it's probably easier, but more time-consuming, to do it this way). This is also a good one, but the explanation is limited to lots (though, you can use the same method for households and rooms): https://jenba.tumblr.com/post/121635635022/how-to-extract-tray-files-for-upload This one doesn't use the Gallery.
In reaction to the comments above, messing with the tray folder should not normally affect your saves, those are completely different files, in a different folder.
And having a very full tray folder (just like the screenshots folder, saves folder, cache folder) can slow down your game or even cause issues.
It is probably a good idea to make it a habit to clean the cache folder and delete the localthumbcache.package file after every play session. And make regular backups (I usually do them before every patch, so approximately once a month) of the saves, screenshots and tray folders (and mods folder, if you use mods).
