I can't find my sims? [ Edited ]

[Destiel2014]

Hello!

I'm having a problem finding the sims that I have made and I have saved for the sims for CAS demo.

I went to the usual location in the library. And noticed that the only sims there were the default sims made by maxis. 

I have checked through all of the folders off to the side and still cannot find them. 

I also checked to see if it was a glitch by exiting and re-loading the game 3 times.

Any help?

The should be in the following folder: documents\electronicarts\thesims4casdemo\tray

There's 5 files per household. Do you have any files in there ?

Hello again, I checked the files and there wasn't a "tray" folder. The only folders in there were:
_Installer
Data
Game
Support
I did check in each folder to see if maybe it was in one of those. However, it was not.

You're checking in programs. You need to check in documents

Alright I have found the tray folder. There are alot of .sgi & .hhi files. But how do I open them into my cas sim game?
